if you must, try HOARD, you're a dragon and you fly around and burn stuff down. it's sprite-graphics. it has upgrading and levelling.
The reason I never looked at steam is because I was expecting nothing to be there, I guess steam has gotten better at filling small niche games. Cool, well I am going to check up Cladun X2, I like how customizable it seems.
Still think OP is dumb and FTL is the best indie I've ever played, and is an Action RPG.
