Well, I say the same thing every time an interesting game hits Microsoft's XBLA or XBLIG services.
The fact is, I don't turn on my Xbox 360 all that often. In part that's because the system is in our basement (lame reason, I know, but it's cold and dark down there!), and in part it's because I just don't have much interest in it or its games these days.

My Xbox 360 won't be dusty for much longer, though, thanks to the digital trifecta that is Fez, Sega Vintage Collection: Monster World and Spelunky.
Oddly, I've only bought (and barely played--surprise, surprise!) the most recent of these releases--that being Spelunky--thus far. Mark my words, though: Both Sega Vintage Collection: Monster World and Fez will follow suit later this week.
Have any of you played one or more of the above-mentioned titles? If so, what did you think of them?
