Tanks in Online. (i regret nothing)
Unrealistic physical damage to cars, I hit a metal railing at a high speed, yet my car only suffered a small dent.
The fact that you need an IPhone for training Chop, customizing your license plate...
Can't drive trains, I found it being easy to get from one island to another in GTA SA.
Classic GTA style cheat activation, it was alot easier and less of a hassle to put a code into your phone to use for later.
Dynamic music isn't a serperate option, and no option to keep the radio on a specific station. I like listening to the dynamic music, but it gets annoying having to change volume because radio music is alot more louder than background music.
No friendly fire option for Online, passive mode doesn't help when your vehicle explodes or getting ran over.
Some small detail is ignored, the red lights for train passings don't work, car steering wheels still don't turn, brake lights for vehicles that the player is driving still don't work...
Damage system for the player. Unfortunately, falling off a bike and landing in dirt does more damage than jumping off a 30 foot building and landing headfirst into concrete.
The Annihilator isn't in Singleplayer, nor does it go as fast as it originally did.
Missions seem tedious in Online. Go here, kill this guy, steal his van, bring it back, here's 1000.
Lobbies automatically invite the same people that left the previous game, it makes me feel like an annoying creep.
Security Guards are counted as cops.
-Cops on foot only appear on the map when you drive near them.
-1 star wanted level takes too long to lose.
- If a squad of cops despawns from going to far, another gets dispatched to where the player currently is. Police helicopters constantly de/respawn and chase your helicopter even when the police are searching
No female cops (except for ones that spawn at police stations)
NPC's go full douchebag when the player walks by, I was just walking along near a train station and someone called the police for no reason at all. (And yes, I died)
Some random events, I accidentally bumped into a gang van and got annihilated moments later.
No crouching, good luck attempting to hide from cops
...crop dusters don't spray dust
That's all I could find
