Far Cry 2

Well this one is really a mixed bag for recommendation; on one end you have this vast, beautiful Savanna landscape to explore, receiving and completing missions at your leisure, and a graphics engine which truly delivers one of the xbox 360's finest looking games. Then the main issue pops up... the game is slow, immersive as all hell, but slow so i only recommend this revive title to those who enjoy a nice story-driven adventure for it's campaign but recommend it to all of Revive for it's multiplayer component which really has a lot going for it; a complex map editing tool to create your own landscape to fight on and a community which rivals Halo Reach's in terms of custom created content. Hell if you're good enough, your map could even be approved for ranked matchmaking so go out and find this game, but i would strongly recommend you try it somehow before buying it

Oh and here's an image that shows just how creative you can be with the map editor, doe this look familiar?
