I'll regret for the rest of my life because I gave my beloved PS One for one big nothing some 7-8 years ago instead of keeping him and playing sometimes.
I kept my Memory card which has 24 slots to save games, but no purpose with the console.
Legendary Tekken 3, one of my 3 favorite games on PS1. ISS 2 and Tekken 3 were the most played games.
I also remember legendary Metal Gear Solid, Hogs of War, Gran Turismo 2, Driver, The Italian Job, Spiderman 1 and 2, Twisted Metal 4, Medal of Honor 1 and 2, Smack Down 2... It was a hell of a fun between 2000 and 2006.
PC games, uhhhhhh... I haven't played strategies for 15 years but I remember my favorite Age of Empires 2, then Red Alert, Stars Wars Galactic Battlegrounds. Even Desperados: Wanted dead or alive was one of my favorite titles.
Moto Racer 2, legendary Fifa 99 and Unreal Tournament, Resident Evil 2... Those games I played on my first Pentium 2(Win 98) in the late 90's. Not to forget the game I probably played even in the next 8-9 years - Championship Manager 01/02.
