I loved the 360!
I'll add to the list.
-1000s of super cheap mobile phone quality indie games (they were terrible and I love them)
-That brief period where we all were playing 1 vs 100. I planned my whole day around being at home to play that game. Scheduled group gaming needs to make a come back!
-Custom face plates for the original model
-Dance Central: the last time my house was full of "cool people" playing video games and having fun.
