There's actually a few things I already liked better with GTA4 and older 3d-gtas
The cars are too strong in this game, they never gets destroyed from impacts, at least not comparable to the older games and now I'm not even counting upgrading the armor level.
Cops are way stupid, easily avoidable and it takes too much time to raise the star-level
The scope on the rifles are actually worse than no scope (in TPS) - it's just in the way, makes the weapon larger
Ironsight/Scope are worse than hipshooting (in FPS) - cause the white/red dot disappears.
The way you get and find missions takes too much time and it's annoying to have to replay some missions and heists over and over again cause different people host.
