Ok I'll go first the game I'm thinking of is a ps1 fighter, One of the characters was named Vincent Valentine, it wasnt Ehrgeiz, and I believe the final boss was a little girl though I could be wrong. It was a blast to play competetively.
Another game is a RPG that focused on collecting pokemon like monsters for the ps1, Jade- something.
One last game for now: A Dreamcast game that involved grafitti and skating. I think I should know the name of this one but it was a couple years ago.
Please help me out and post descriptions of games you want to find.
