Tekken 2. Yes. There are many good ps1 games. Rayman being one of them too. But I guess Tekken 2 was the real exclusive to PS that I liked. Oh and crash bandicoot 1 and 2 and spyro both of witch got a remake they deserved, but yeah.
OH and does anyone remember Fighting Force?
And one of my old favorites as well was Sub Zero Mythology. A lot of ppl hated this game, but I loved it. Especially if you emulate it now a days so to cheat it with quicksave and quickload, so you don't need to relly on stupid console checkpoint system, that is amazingly still present today on many titles. I know it adds to challenge, but IMO it really needs to DIE. You can express creativity without ever revisiting this annoying feature.
