Oh man, so much to choose from.
I really enjoyed Twisted Metal, Descent, Full Throttle,Star Wars: Dark Forces, WipEout, Rayman, and Tekken 2 at the time. I think Tekken 2 is my favourite - and it's certainly the one I rate highest on my top 50 list every year - but I only played the PS1 version, which was in 1996.
