An indie game out there called Krater is pretty fun. It's more on the RPG side of things, and to be fair I'm not too deep into it yet, but the upgrade / crafting system is really pretty neat. The graphics and animations are solid, and the combat is interesting so far. Looking up the reviews, it seems like it either got top end grades or people pissed all over it, so the metascore is kind of misleading I think. Anyway, if you can catch it on sale or whatever, would recommend.
