Sawbuck Gamer, the AV Club's bi-weekly collection of cheap or free games, mostly for browsers and iPhones. It's where I found Canabalt (which I still <3) and there are a few others I've tried which are neat. Dig through the articles and you'll probably find something fun and unusual.
Don't say "I QUIT"...put it away and try it again some other time. I've recently started playing Final Fantasy VIII again, and it's become worth the effort to work through the problems I never could figure out.
