I've never liked PSX games. Either the same thing had been done better on another system, or the games were just plain bad.
Their was too much focus on 3d, especially for it being as underpowered as it was, and the controllers were the most uncomfortable things I've ever used.
Supposedly their sports games are good, but seeing how I don't play that genre, I can't really comment on that. Sure, there might be one or two decent games for it, but they were nothing to shout about.
