The series didn't last long, but Gex games was fun to sink hours into. The second and third game played like Mario 64, except you are playing as a lizard who spent too much time watching TV.
For PSP, PSVita and PS3, it's available in the PSN store and the PC version is available in GOG.com (https://www.gog.com/game/gex)
