I honestly love Overgrown, Crash, Bailout, and Storm. Salvage is alright I would prefer another other than that, but I like them, and they were worth it to me.
Spend it on an Indie game. D2D is having sales for the next few weeks, you could probably find a nice deal for $15 or less in one of those weeks. Last week they had DiRT 2 for $15.
