my first ever was gta 3 on pc, but i was like 8 yo and i didn't speak english back then so I quitted immediatly. The first one i enjoyed was San Andreas with subtitles, great game.
The first GTA game i played was gta4 and it seemed pretty nice. The only thing i remmebered about the game was how grey everything was, and so i think they did a good job with the graphics when gta5 fianlly came around
ive been playing GTA since GTA1, the first one is cool but i remember enjoying the second one way way more. it only got better after that though. absolutely incredible game franchise
