I think GRAW is great, very challenging and graphics are nice. My friend borrowed it from me and he cannot see why it got such a low score. Gameplay is great, sound effects are good, you have to go for cover and it has good squad action, I don't know, I really liked it. I miss the original Ghost Recon... I'd recommend then you d/l the demo and try it, but I genuinely enjoyed the game and I'd highly recommend it, in many ways it is much better than the older games. I own it for the PC and although its a high end game requiring more power if you want to enjoy it fully, the XBox360 version is more like an action shooter, gameplay is quite different, using 3rd person for example and less squad based employment.
Rainbow Six: Las Vegas should be really good too.
