It actually sold more then that, its one of those early undertrack 360 games.  Still pretty obsure though I'm thinking even with the corret numbers and including digital sales the game probably sold less then 500K.

Yeah, XIII was really fun game.

wait, is this game available in XBLA??? O_o i didnt know that

I don't know why but I felt the game was very enjoyable despite its strange premise.

Now that I think about it... probably Shenmue. The story is kinda weird, but at the same time pretty epic. That's what I love about this game, making it one of my favourites.

Vespers. It's a text adventure set in a medieval monastery during a plague outbreak. You can Download frotz to play it, it's free.

Yep, its been available on XBLA, Games on Demand for some time already.  Kinda pricey though since its still $19.99.  Should be $14.99 or less since its pretty old.

Just looked that one up. It looks pretty out there. Are you supposed to date pigeons or something?

One of the first 360 games I bought!  

My answer: Incredible Crisis.  Weird and addictive!

Yeah, Sega had their A game back then. Lots of weird ideas in games but they were so fun. Like in Shenmue you drove a forklift around and collected capsule toys. Who woulda thought that up?
