Old Videogame in which you play as a green dinosaur or lizard?
No it is not Yoshi, but is very similar to him. It came out around the time when the ps2 was a new console.
No, it isn't Gex, but thanks i was gonna ask that game too xD. If it helps the game was a 3 person perspective game, all i remember i one level in which there where floating rocks and i had to climb them then there was this bridge with lava and to pas the level i had to get to the other side. Something els i remember is that in a level you couldn't get touched by shadows or you would lose or fall endlessly.
Found it, it was only for ps1 it was Croc 1 and 2
