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.
Awesome Music: As a Sonic game, this is pretty much a requirement. Although some may consider Episode I's instruments to be full of a sound resembling that of dying cats, Episode II's usually don't have such sounds.
The final boss of Episode II. On top of being really funnote Although, that's not to say that the others in the game weren't, it's one of the most creative bosses in any of the Sonic games thus far. The awesome music playing also really helped.
Broken Base: This game has probably gotten the biggest amount of praise and backlash at the same time with just three seconds of footage shown with a tons of people analyzing and nitpicking every aspect they can get their hands on judging from the trailer alone.
Later, the game gets delayed for tweaking, fine-tuning and an iPhone release. Many of the fans find it a time for rejoicing, as they have hopes that SEGA is actually paying attention to the complaints. Other fans are upset with SEGA for hyping the fanbase up over a delay, and they felt the game would've been fine coming out as it was.
On a smaller scale, some people think that the music was a bit stifled and wasn't mastered well.
No Wii release for Episode II prompted this, as Wii owners questioned what made it impossible to do on the Wii when the first episode worked fine - It's largely down to the new graphics engine & better quality music files making the game too large for the Wii Shop. This has conversely opened up a camp of people blaming the Wii for the poor graphics & music quality of Episode I. Another subset of the Wii owners are complaining that because Episode II isn't seeing a release on the Wii, they won't be able to access Episode Metal without repurchasing Episode I. (That said, nothing has been confirmed about a Wii U re-release yet, so there may still be hope.)
Contested Sequel: Both fan and critic reactions vary when they're asked to compare it to the previous 3 installments.
Ear Worm: This game has some too. In particular, the "Pinch" boss music in Episode I (and standard boss music in Episode II), a nearly 20-second loop of repetitive notes to the point where some people think it's shorter than it actually is. It's fine as for its use as a boss theme, but it ends up being used as the EGG Station's BGM until you reach the final boss, which of course takes longer to get through than finishing off an angry end-of-the-stage boss.
GameTrailers's Episode II review gets this too, with the review full of constant comparisons to the Genesis games, and the score being lower than Episode I's.
Game Informer's review of Episode 2: a 5! To wit, five is definitely not an "average" score.
Even Better Sequel: Most fans consider Episode II far superior to Episode I thanks to its vastly improved graphics, less derivative level and boss design, a new physics engine that more closely resembles the Genesis games, and the ability to play as Metal Sonic.
Faux Symbolism: The final boss of the Death Egg mk.II Zone is a heart. A realistic, beating, human heart.
Freud Was Right: Sonic and Tails' double spin dash has already been called "the 69 attack" in a few forums.
Game Breaker: You can press Retry before time runs out in special stages, providing infinite attempts at each Chaos Emerald as long as you don't touch the exits.
The Rolling Combo in Episode II. Immune to almost every hazard? Check. A constantly moving Spin Attack that can take down even Snowy in one hit? Check. Makes the Stardust Speedway remake race incredibly easy? Check.
Also, as usual, Super Sonic. This time around it's taken even further since he can no longer drown (meaning the only things that can kill him are Bottomless Pits and being crushed) and he automatically lights up Lost Labyrinth Act 2.
Super Sonic got even worse in Episode II, as now he's playable in boss battles and he does DOUBLE DAMAGE to all bosses.
Goddamned Bats: All of Casino Street Zone has Batbots everywhere, and Mad Gear Zone has the Slicers that'll ruin your day. Asterons, also in Mad Gear, are surprisingly less annoying. Shellcrackers are less threatening too compared to Metropolis Zone.
Episode 2 did not come to WiiWare. The hatemail came in droves.
Taken even further after the first gameplay trailer of Episode 2 was released and the confirmation that Tails won't be playable in Single Player mode.
The "Episode Metal" announcement has induced this even more with Tails fans.note Tails isn't playable outside of 2-Player Co-Op mode, but Metal Sonic is playable in single player and gets his own story campaign to boot. The fact that you need to own both Episodes 1 and 2 in order to unlock "Episode Metal" hasn't sat well with some either; especially Wii owners.
It's the Same, Now It Sucks: What part of the fanbase thinks of the first episode. The stages, for example, have been accused of being carbon copies of the Genesis/Mega Drive stages instead of original stages like they actually wanted.
Scapegoat Creator: Dimps became this after this game, after a successful run on the Sonic Advance Series and the Sonic Rush Series. With every Sonic game they have made since then (most notoriously the 3DS version of Sonic Lost World), the games's shortcomings have been blamed on them, even though it was Sonic Team's current leader who admitted that he wanted the game to have a different feel than the Genesis games.
Scrappy Mechanic: The camera is just a little too close to Sonic for some people, causing people to barrel along without having enough of a view for what's headed for them.
The Homing Attack from Sonic Adventure onwards bolted onto this decidedly old school game also qualifies, though most people aren't really upset about lock-on dashing as they are the horizontal leap you can take when you're not even locked onto anything.
Sonic uncurling in mid-air after flying off a ramp or attacking an enemy. It's designed to force players to rely on the homing attack, but if they're a little too familiar with classic Sonic gameplay, they'll be shedding rings at least five times per act.
His acceleration feels significantly slower than the classic Sonic games, or side scrolling Mario games for that matter. Good for the Scenery Porn. Bad for a character who is supposed to be fast. Compare the generally faster gameplay in the classic stages of Sonic Generations.
So Okay, It's Average: The general opinion on Episode I. While it's a perfectly playable game on its own, it completely fails at being a follow-up to the classic games in that its core gameplay is similar to Sonic Rush without the boost, and it tries to mask this fact by having derivative graphical designs from stages in previous Sonic games.
Spoil At Your Own Risk: The aforementioned user in the Fan Dumb entry spoiled the game when Sega employees threatened warned that something bad might happen if he spoiled it. He ignored them and as a consequence, the entire Sonic 4 board of the aforementioned site was shut down due to the uproar. Then Sega went and fixed some things that were complained about the leak, so it appears that the net effect was that good things happened, not bad.
Surprisingly Improved Sequel: In the case of people who though Episode I was mediocre at best. When they said they were improving Episode II, they weren't kidding: better graphics, better stage designs, better physics, the ability to use Tails as a power up and play him in multiplayer, more creative boss fights, Red Rings, small nods to older games, and Episode Metal to name a few.
Also better music that relies less on the Sonic 2 snare sound as well as fewer "gimmicks". There is nothing like the torch puzzle or the water puzzle in episode II.
That One Achievement: In Episode I on the XBox 360, you get an avatar award for collecting all of the rings in the pre-credits area. What makes this annoying is that Sonic moves on his own, so you're done if you miss any, and if you don't get it, you have to finish the final stage all over again just for another shot at it.
That One Boss: The Death Egg Robo from Sonic 2 returns as the final boss. And he's even harder in this game, even though you actually have rings this time when you fight him...
And before that, the boss of Lost Labyrinth Act 3 can be really hard for some as well. Make one mistake and you're squashed by the walls.
The Episode 2 final boss is shaping up to be this. As is Metal Sonic's Badnik Carrier.
Every Metal Sonic boss fight. If your relflexes aren't up to par, you'll find yourself dying a lot.
True toDimps tradition, the special stages in Episode II range from trivially easy to somewhat difficult until you get to the last one, which is nearly impossible.
Same goes for Episode I. It has the most complex design and a ton of bumpers next to exits. The low time limit doesn't help things. The physics are odd as well: Sonic bounces when hitting walls and when grounded on them, he sticks too much, which results in very imprecise, time-wasting controls.
Sky Fortress Act 3, from Episode II can be difficult for some people, especially for badly coordinated players in 2-Player mode.
They Changed It, Now It Sucks: A lot of the complaints from the three seconds of footage alone range from Sonic having the modern design in a sequel to the old school games, Eggman not being called Robotnik, that it looks like it'll become a "Sonic Rush 3" and that it has the Homing Attack. Some are even complaining about how the game is using a sleeker HUD instead of reusing the admittedly blander one found in the older games.
This is what reviewers seem to think of Episode 2 in comparison to the first episode.
