If the game is beatable within a rental and you don't want to do much with it after that, you could always rent it. Having a rental subscription, I don't have this problem. I'll play through a short but fun game, complete it, send it back after having my fun for 3 days or whatever, another game on the way, badda bing badda boom. No worries. Short but fun games are great without the commitment. lol. When I get a Wii, I'm gonna add a bunch of these rail shooters to my rental queue whether they are short or not. They look like fun.
