Jet Grind Radio is my favorite game of all time. I don't care that people think it no longer holds up -- its place is solidified in my mind as number one. It's a decade old and still has more style and better character design than most games today.
Zineth is very much inspired by Jet Grind Radio. It's stylish, it's clean, and oh yeah, you skate around the environment. Zineth also has a bizarrely addicting, yet simple, Pokémon variant. My only wish is that this wasn't just an experiment and was instead a full-fledged game.
