These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ellie turning out to be Not Quite Dead. It actually seemed as though the creators planned on having her die, but then they changed their minds later on and sloppily forced her back into the plot at the last minute.
In Awakened, Carver and Isaac's survival. Lampshaded by Carver, who is incredulous about how they were "saved by fucking aliens", but Isaac notes that he has decided on Giving Up On Logic a long time ago.
Alternate Character Interpretation: For the game as a whole. Was Dead Space 3 an Actionized Sequel, or simply the result of Isaac having tangled with the Necromorphs twice before and survived both? The ending of Dead Space 2—where Isaac defeats them more or less on his own terms—reinforces the ideas that the Necromorphs haven't gotten any less frightening; Isaac just knows that he can get through this if he keeps calm and uses the resources available to him.
Broken Base: It's EA. They're voted the worst company in America for good reason.
The addition of co-op definitely rubbed longtime fans the wrong way, especially given the Broken Base over Resident Evil 5's co-op. The developers try to assuage everyone by insisting that the singleplayer is still the same as the previous games, and that co-op is implemented as seamless as possible. Some fans think Visceral are capable of pulling it off, but others are still unconvinced.
EA admitting they're going to kill the franchise if Dead Space 3 doesn't sell five million copies (keep in mind both 1 and 2 both sold about two million each) haven't made anyone happy. The EA ,however, has stated that that report was "patently false." Guess we'll just have to wait and see.
Fans have also taken issue with the introduction of Take Cover, Unnecessary Combat Roll, Universal Ammunition and enemies with guns, who feel that this turns a Survival Horror franchise into a generic Third-Person Shooter. EA admitting that they pressured Visceral (see the above link) to make the franchise have "a broader appeal" is not seen as a promising sign in this regard, with nicknames like "Gears of Space" spilling out of detractors' mouths. Not helped by the fact that they lied about universal ammo, originally claiming it was just in the demo as a placeholder. To be fair, though, the grand majority of enemies with guns are killed by Necromorphs making them an almost non-presence in many cases. It should be noted that enemies with guns existed in Dead Space 2 and they aren't much different then long-ranged Necromorphs.
A lot of people have taken offense to EA deciding to market the game by sending early demo access to famous YouTubers (via TheGameStation and presumably other networks) like Game Grumps, PeanutButterGamer, The Completionist, Criken, and PewDiePie, etc. While some fans are thrilled these players are receiving some sponsor money, others are annoyed at them and EA for making them "sell out". It's mitigated somewhat with most of those YouTubers harshly critical of the game (either choosing to be honest about their contempt for the game, ex: ProJared, or choosing to be more subtle, ex: Game Grumps), and some made extremely short episodes about it as opposed to their normal content.
Crafting now has microtransactions so you can buy components with real-world money. Sure, you can find plenty of components in the game and microtransactions are there for people too lazy or impatient to find them on their own, but seeing how microtransactions equal pay-to-win for some, it just leaves a bad taste in everyone's mouth when talking about it. To make it worse, the official stance is that the microtransactions are there to court mobile phone gamers. For better or for worse, Visceral has officially stated that the idea to add microtransactions came from them, not from pressure on EA's part.
EA have announced they will be offering eleven pieces of day-one DLC. One of the developers for the game let slip that all the DLC would cost around 45 USD total. This is just under the price of the game itself. The dev then said that Visceral didn't care about money. Announcing the first story DLC, Dead Space 3: Awakened, would be released in a month for 10 USD when people just barely got their hands on the game itself didn't help.
The last Dead Space game also had shoehorned-in mutiplayer, but it didn't have any achievments for it because, as one of the devs secretly put it, "We don't give a shit about multiplayer achievements". Well, this time around there is indeed multiplayer with achivements for it...looks like EA forced THAT on them too.
To illustrate why the base is broken, instead of unanimously hateful of the changes, many players never really considered the Dead Space franchise to be much of a "survival horror" game in the first place, so any added variety to the combat and general gameplay in what can also be considered an atmospheric, sci-fi Third-Person Shooter is a welcome change.
The end of Awakened. Some find it fitted with the Cosmic Horror-inspired atmosphere. Others found that after the bittersweet ending of the vanilla game, having the Moons reach Earth with the implication humanity's doomed despite everything Isaac and the other protagonists have done negated any sense of accomplishment from the entire series.
Complacent Gaming Syndrome: Visceral have spoken out against one-weapon playthroughs, stating that the new weapon design system exists specifically to combat this. Ironically, one can build extremely overpowered weapons through crafting, making a one-weapon playthrough in this game far easier.
One of the pre-order/day one purchase DLCs is a weapon that's probably the best one in the whole game and is available from the start. No need for crafting, besides adding damage or clip modifiers.
The unnamed alien race from Tau Volantis is something of a version of the Protheans of Mass Effect, taking into account the "Reaper" analogue. They lost their battle against their obscenely powerful foe, and it is only through a psychic vision (which occurs in much the same way) that The Chosen One can learn how to finish their work and their battle. The only difference is that Isaac, unlike Commander Shepard, doesn't need anyone to interpret what he saw, since it's relatively clear at the time.
The Brethren Moons themselves are quite literally a race of the titular creatures fromHellstar Remina. The writing team of the game may very well have at least one fan of that manga...
The Twitchers are back too. This time around, they're more powerful and seem to have the same amount of health as an enhanced Slasher, and they tend to attack in packs of four or five. Even with the stasis, taking out an entire group of Twitchers can be difficult.
Stalkers have returned as well. They're more aggressive in this game, and they're smart enough to jump behind you and hide behind cover you just walked past. In other words, they can attack you from behind if you don't notice them. On the upside, a shotgun can take out a Stalker with just one blast.
The Alien Necromorphs encountered in the underground city. Unlike typical Necromorphs, you can't dismember them. All you can do is slow them down and randomly shoot at them until they die (or until you run out of ammo). The fact that certain areas have these enemies spawn over and over again just makes them all the more frustrating.
Family-Unfriendly Aesop: Initially brought up when Ellie and Isaac meet and agreed on by Isaac near the end of the game. Isaac initially refuses to continue fighting, an understandable point as his life was a living nightmare at several points, he's lost loved ones (Ellie included as she left him), and has tolerated being the victim of Chronic Backstabbing Disorder more than once. Ellie's response? He's a coward who can't or won't face his problems. Apparently, if you have post-traumatic stress disorder, you should just stop having it and man up.
Even though we have no evidence that Ellie knows about Lexine, if she is alive, the fact remains of the second part of the Aesop's acceptance in the spoiler listed here.
Awakened has also been subject to this, as it provides an epilogue to the main plot. Undoing the incredibly Bittersweet Ending where Isaac and Carver seemingly die killing the final necromorph, toppling them forever with a Not Quite Dead reveal, you aren't going to win many points with fans. When you then provide a final Downer Ending where everything was probably for nothing, as a Brother Moon has found Earth and then have Word of God making it dubious if the series is done due to recent unpopularity, you're going to have numerous fans desperately trying to scrub it from canon.
Game Breaker: Hammond's Heavy Chain-gun = Hammond's heavy frame + Telemetry Spike + Diffraction torus tip + Ammo box attachment. You'll be dropping ammo clips because they'll start clogging up your inventory due to the ammo-expentiture:kill-count ratio of this gun.
Genius Bonus: Rosetta, the alien lifeform that allows Isaac to decipher the information about what happened on Tau Voltanis is likely named after the Rosetta Stone, an artifact that showed researchers how to understand Egyptian hieroglyphics.
Necromorphs still have a problem with differentiating when a person is in a room or not sometimes, outright abruptly ignoring them... even if they are a foot away from its face! Which allows the player to shoot off limbs with their back turned.
Necromorphs don't ragdoll properly when killed by gradual damage such as fire or acid, meaning they'll amusingly flop into the air like a fish when they die.
Most Annoying Sound: The Exploder's yelling, especially in the segment where you have to fix the shuttle. There are dozens of Exploders, often crawling through the ducts so you can't shoot them until they come out, but they still continue to yell loudly.
The Wasters are quite terrifying, with their almost-human appearance, growling and muttering, and their intelligence... until you cut them in half and tentacles sprout from their legs. And they walk towards you backwards. Try to see that without thinking "the pants were dead".
Porting Disaster: Averted. While Visceral Games made statements that the PC version the would imply it to be lackluster, the PC version runs very smooth and comes with a nice amount of options.
Unfortunately when playing in full screen mode if an alert interrupts the game, there is neither way to get back control in the game nor a way to quit it without logging off or restarting the computer.
Player Punch: In Chapter 15, after Carver and Isaac make it out of the laboratory as it's filling with deadly gas, Ellie realizes she can't make it and tells Isaac to leave her behind. The game then forces the player to Press X to Not Die, which causes Isaac to seal Ellie inside just as she tells him "I love you."
Romantic Plot Tumor: The Isaac/Ellie/Norton Love Triangle isn't much beloved by fans, especially for what it does to Norton and Ellie. It becomes a large part of the game's conflict, despite being a new addition to the series, and Ellie and Isaac's prior relationship being entirely off-screen.
Ellie is approaching this, mainly for breaking up with Isaac between the second and the third game and hooks up with Norton. Ignoring Isaac and embracing her new boyfriend for a kiss in front of him didn't endear her to many players, nor did her flippant attitude about Isaac's Shell-Shocked Veteran status. Some fans also do not like how less active in fighting the Necromorphs she has become. To be fair, Isaac got over his shell shocked status in the last game and falls right back into it after having a few more years out-of-story to deal with it. Also considering what Isaac has been through you would think she would understand.
Norton gets a lot of hate not just for the enforced Romantic Plot Tumor, but also for being perceived as whiny, cowardly, incredibly possessive towards Ellie and one of the biggest assholes in the series. The fact that he betrays Isaac to Danik then attempts to personally murder Isaac even after Isaac had saved him from both Danik's treachery and the giant attacking Nexus, only further compounds player hatred towards Norton. You can easily lay the blame on Marker influence.
“Stop Having Fun” Guys: A rare developer case. Visceral states they introduced the weapon crafting to force players to review and rethink their strategies throughout the game, as a way to combat Complacent Gaming Syndrome. The problem is that the exact wording of the statement implies that whoever did a Plasma Cutter-only run of the previous games was apparently playing them wrong, despite there being an achievement for such a run in the first game, and a special ability for fully upgrading it in the second.
Since they didn't implement situational requirements for fighting specific enemies, most players still just find the optimal weapon combination that suits their playstyle and stick with it.
Take That, Scrappy!: Have fun shooting Norton in the face. Again in Awakened, who's the first Necromorph you get to kill? That's right, Norton!
That One Level: Disposal Services. It's wave after wave of constant Elite Mooks who soak up crazy amounts of damage in every single room. Enjoy having to restock on ammo multiple times just to progress. It's worse because the only reason Isaac wants to go down there is to find more ammo and supplies. Ammo that he is doubtlessly using up just by going down there. There's not even any really interesting logs, just an enumeration of the threat levels for alien containment (level 5 being "kill everybody and everything and even the databanks", but we already knew that).
