The list author says: "Some of the best Xbox "exclusives" are co-released on the PC or time-limited before they eventually get ported to the PS3 (eg, Elder Scrolls IV, BioShock, Psychonauts, Splinter Cell, GTA4 dlc, etc). But the software interface is second to none and console has an impressive line-up of games you can't find anywhere else.
This is a list of the 360 exclusives that make it worth owning:"
"2011. Outstanding! The defining third-person shooter to which all others in the genre this generation are compared. There is a ton of value on the disk between the single-player & co-op campaign, horde mode, beast mode, various multiplayer versus modes, and continued support by Epic."
"2008. One of the best, most influential 3rd-person shooters available on any platform. The single-player is great, multiplayer is great, co-op campaign is great, and co-op Horde mode is a blast. Loads of value.
Metacritic = 93. Don't believe the rating. It's better than the first."
"2008. Co-released on the PC. Reason enough in its own right to get a 360 if it wasn't available on the PC. Outstanding 4-player squad-based shooter, it forces you to work with your team more than any other in the genre. Sadly, free DLC on the PC costs on the 360.
"2010. An under-appreciated, story-driven game from the studio that brought us Max Payne. Part survival-horror, part action game that draws inspiration from many sources, including Twilight Zone, Stephen King novels, and LOST."
