I like GRAW 2 if I want to settled in my chair and have a quiet time killing... But for all out action I find myself playing Armed Assault in COOP Mode... You can drive/fly climb towers and enter buildings for strategic points... Has tanks, strikers, choppers, A10, trucks, bikes, hummers and ALOT more you can move around in... And the arsenal of weapons is awesome and more being developed every week... http://www.armedassault.com/features.html Maps are like 450+ km sq.... Also comes with a mission editor... Totally immersive and TONS of MODS.... http://www.armed-assault-zone.com/news.php
