To Me my mega ultra favorite game was a little Ps1 gem called Battle Arena Toshudien it came with my ps1 and I just played the hell out of it. xD I still play it to this day , sad that the sequels are **bleep** tho :/
MediEvil. It's not a 5 star game, but I had a whole lot of fun playing it. Maximo and The Mark of Kri on PS2.
Probably a ton of others, but those three are the first ones to pop into my head.
MediEvil wasnt the most popular game back in the days but it certainly had it fanbase.
36 pages of favorite games and most of them are ps1 and ps2 games. And some do not thing bc would be a good idea.
FF7 would be my favorite on ps1 because of the vast story and gameplay.
Kingdom Hearts or the Xenosaga series on ps2.
Metal Gear for ps3. But there are so many good ones that it could change from day to day as I remembered them again.
I am fixing to play the last of us so the ps3 favorite may change after that.
