Approaching a Xbox 360 milestone

I just bought Syndicate and I realized my Xbox 360 collection is approaching a nice arbitrary round number. When I buy Mass Effect 3 in a couple weeks I'll have 50 retail games. I don't want to do the math to find out just how much I've sent on games this generation, and I did buy quite a few of those games on sale or after price drops, but even so, that's a lot of money. I've beaten 32 of these games, or in the case of some of the sports games I spent a significant amount of playing time in game. Somehow I've managed to do all that with my original Xbox 360 and I only had to send it in to get fixed once after it red-ringed about a year ago — I didn't have to pay for the fix.
