Why do you guys hate on this service and compare it to XBLA, without thinking about this: The best game for XBLA in the first 6 months (and only one I bought until street fighter 2 came out) was freaking Geometry Wars. And that was out for the Xbox. The other games were just games you could find on a computer in HD and multiplayer mode, not that great.
If you could find practically every single Xbox 360 XBLA game on the computer, but play them in HD on a 360, it must be a great deal. Not saying that Nintendo hasn't rehashed every single one of these titles continuously, but still...
