If you asked me this 6 years ago, I would say GTA IV.
But now its definitely GTA V.
GTA IV felt like a downgrade compared to San Andreas, and it literally was in a few ways(like the map size). But it still felt like a traditional Rockstar game.
GTA V is an abomination to the series, with its cash-cow online mode and its half-assed story mode. I plan to never touch the game again.
Exactly. I don't want to jump o nthe hate train too much, but the SP def. was disappointing (partly due to my too high expectation I confess, even tho I'm a PC guy and have been forwarned)
GTA IV was not a bad game, but just not my favourite setting (NYY/present time) I dunno, it didn't have that special "GTA flair", and felt just like any other Action game, albeit a very high quality one.
Wish they would go back in time again and do sth. like Vice City.
