I'd say getting an Xbox is totally worth it, the only thing not worth it is Xbox Live, considering it's free on every other console. My Xbox stopped reading games so I sent it back and got it repaired for free, but I'm not sure if the latest Xbox has as many problems as the old one. Good luck making more Castle Crasher flashes :3
Also some good games are: Super Meat Boy, Castle Crashers, Halo, Gears of War.

Well companies make their products imperfect to make more money with there newest version and i think you should wait a little bit maybe around 20 years or so :3
