...Why would you buy a game that overpriced when you could just get it from a store?

This game was online???? 
 
Wow.. that might answer your question. I owned this and wasn't even aware.

I pop it in every once in a while and get random messages "Player <name> wants to join your game! Allow them?" (I always deny but whatever) and it happens pretty constantly so I assume there is still some people playing. However, it is a co-op game for 2 players only, something I figure most people might enjoy more playing with someone they actually know. 
 
Also you don't want to buy it on games on demand for different reasons. The game was not able to install to the HDD when NXE originally launched for some reason (don't think anyone bothered to go into detail as to why) and recently they finally added the option (I assume when it launched on demand as well) and after installing the game it completely breaks some parts. For example you can climb on top of buildings and look off too literally the other side of the game, however I noticed for whatever reason when the game is installed to the HDD areas off in the distance are not textured, we are talking like half a city NOT TEXTURED. There are also other various differences I noticed but those slip my mind at the moment. 
 
Is this same problem on the Games on Demand version? I have no idea, but logic tells me yes it probably is since that is also installed to your HDD. Also the game is like $4 online, even after shipping that is cheaper than buying it from games on demand. Just sayin'

I don't think you can actually use M$ points for games on demand, can you? They are priced in $ and charge your card immediately. At least they have for the ones I have bought (Civ Rev/SF4/Army of Bros). "
