I can't tell you if it'd be worth it for you - but there are a lot of great games on there. I don't personally own many, but I highly recommend Mario + Rabbids: Kingdom Battle. If you have even a passing interest in X-Com style games, or strategy, it's super fun. The combat is tight, transparent, and fluid; there's a fair bit of challenge if you try for everything; and it's just plain funny. Highly recommend.
