It's difficult to say, I've played (and continue playing) more games on my PS2 than on my PS1, but on the PS1 I played my favourite game of all time, Suikoden II, and also FF Tactics, FFVII, FFVIII and Chrono Cross. I'd say they are pretty equal, the PS1 has more 10-deserving games, while the PS2 has more 9-deserving and more overall good games. I can't choose between the two. They're the two best consoles ever made
