Filthy Casual

It's a relatively new but pretty damn fun fan game. It's up to three gyms so far, but should receive an update soon. If you want to check it out, I highly recommend checking out the website to see it's the kind of game you want to check out.

Cool, I’ll check it out soon. How often does it update?

Also will there be more Generations added.
