Simple action RPG with lots of characters, skills, and bosses. I beat it recently, endgame actually requires a little brain power.

Super hard platformer. Has upgrade system to make it a little easier but you'll still get your ass handed to your over and over.

It's not quite out yet but I've played a few private tests of it and I absolutely love it. It's an indie MMORPG mix of Maplestory and Mabinogi. Public test is this summer.
