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.
YMMV: Grand Theft Auto IV: The Ballad of Gay Tony
Base Breaker: Gay Tony himself. People either find him as a whiny, drug-addled drama queen, or generally loved due to his hammy but likable personality.
Best Level Ever: The last story mission is extremely awesome because it takes you from fighting on foot to riding a motorcycle to hijacking a plane to kill the last bad guy. In short, it is basically everything cool about the game in one mission.
Complete Monster: Ray Bulgarin. Laughably Evil aside, he is sadistic, sociopathic, extremely aggressive and... sororicidal? Aside from his whole human smuggling past, his generally jerkass, aggressive personality, his appearance in this sequel makes him an even bigger monster. He soon gets several Kick the Dog moments: namely, the brutal murder of the cook and his subsequent betrayal of Luis, and his cruel treatment of his sister, even shooting at and possibly killing her. It's also implied that he's actually holding his sister hostage in their own home!. Moreover, Bulgarin is not completely pragmatic and makes awful crimes because he is strongly motivated by sadism. The worst part is that nothing justifies his crimes, and, unlike Niko Bellic, he never felt remorse for the human smuggling.
Game Breaker: The automatic shotgun (with explosive shells) mentioned below. All the hitting power of a shotgun, with none of the range limitations, combined with Incendiary Exponent. It can blow up a car or a helicopter in two shots.
Genius Bonus: When Mori beats Brucie in the chess game it is a recreation of famous Karpov-Kasparov 1985 World Championship Match.
Jerkass Woobie: Brucie Kibbutz. He's been picked on by his older brother for years. Not to mention Luis genuinely feels sympathetic and sad for Brucie.
Love to Hate: Ray Bulgarin, again. Sure, no one can deny that he is unpleasant and made several horrendous crimes because he enjoyed it. But curiously has several fans, for his voice and some of his lines who is considered entertaining or even funny.
Ray Bulgarin crosses this when he shoots his own sister out of anger and possibly killing her.
Rocco sets up Luis to kill Tony Prince when an Ancelotti boss demands a body of either Luis, Tony or both of them in a shootout.
Nightmare Fuel: Ray Bulgarin is generally frightening when shows its hand psychopath. In fact, as stated Rocco: "said he wants the head of anyone involved with the diamonds". And this may be true if you played the mission "In The Crosshairs", where he clearly beheaded one of the men who was involving in the diamonds.
Mori isn't well liked by the fandom at all. Put all of Brucie's overconfidence without the charm and humor, add Napoleon complex, jerkassness, and no Morality Pet, and you'll pretty much get a good idea of what Mori is like.
"Going Deep". After a very long car ride, you have to fight off wave after wave of heavily armed, heavily armored NOOSE agents in a parking garage with no extra body armor lying around. And if any of the agents get close, they will tear your health bar to shreds.
But luckily the massive trauma you would sustain is easily alleviated by 2 cans of "Sprunk" from the numerous vending machines.
And there are actually two or three extra armor laying around if you look hard enough.
Likewise, "In The Crosshairs", which involves fighting your way across several rooftops through an army of guys with automatic weapons and grenade launchers, fending off the occasional helicopter attack, and then jumping down a fire escape to street level, where there are yet more gun-toting goons, stealing the nearest car and driving away until the mission ends.
"Caught With Your Pants Down". Yusuf has you acquire an APC, which, unfortunately for you, is suspended high above the city from a sky crane. He expects you to have the Improbable Aiming Skills needed to snipe the cables holding up the APC from a moving helicopter. When you finally do get past all that, you find that the APC is a bit of a letdown, seeing how it's not completely Immune to Bullets, and will take damage from Stuff Blowing Up too close to it, so you have to deliberately hold yourself back from going apeshit with it.
Most of the helicopter missions tend to be like this considering the awkward handling of helicopters. In particular, "Sexy Time" could be this for many fans, as you have to aim downward and maintain both low altitude and distance to hit the boats that are running away, while dodging RPG fire. Because of these mechanics, it's very easy to crash the chopper into the ocean. In addition, the forums often have contradictory advice regarding how to deal with the mission. Many users have compared this to GTA: San Andreas' infamous (but optional) mission "Supply Lines".
They Wasted a Perfectly Good Plot: After being introduced to the fight clubs in order to pay off Luis' mom's debt, Luis tells her to stay away from the local loan shark. The player can later get a call from Luis' mother where she talks about how nice and well-behaved the loan shark is, so you may expect a mission where Luis has to save his mother again from the loan shark, permanently this time. But no, this never happens. Of course, you do have the option of winning the fight and killing the loan shark to complete the mission.
The back of the box also makes it seem like a tale of a man deciding to stay with the rich and glamorous, or helping out his family and friends in his old neighborhood. This little plot is quickly abandoned in favor of getting out of debt and wrecking Bulgarin's shit.
Luis vows to murder Rocco later during the game, yet this never happens and he doesn't even appear as a random stranger.
