Shadowrun Arcade
Shadowrun came out in 2007, it was over-priced, under marketed and had a gimmick that pissed gamers off (cross-platform with Vista). No one wanted to pay $60 (on 360) for a multiplayer only game they had never heard of, and if they had heard of it, the concept of a Shadowrun FPS was blasphemy. On PC you had to buy a new $300+ OS that sucked, pay $50 to play online with GFWL and then buy the game for $50. Obviously the game bombed and was reviewed poorly (although most reviews mentioned its stellar gameplay), it had matchmaking issues right at the start that didn't get fixed for a month.
Outside of all this, the game is an amazing, unique, well designed and impeccably balanced team based FPS for competitive and casual play. It is the most hardcore multiplayer shooter I can think of on console. It deserves more love, and although it is cheap and still has a small cult community, it could succeed if resurrected with an XBLA Remake. It fits the bill perfectly, multiplayer only, not a ton of content, but still plenty and hard hitting original gameplay that would fit XBLA well.
Update it with some individual career stat tracking, better matchmaking and custom game options, release it for $15 and it should do very well. If it does exceptionally well, finish those rumored 5 almost done maps FASA had before they closed and release them as DLC packs, 1 map Free, then 2 packs paid with 2 maps each for 240-400 points.
