It doesn't feel similar at all (which is a great thing because GRAW2's aiming sucked). It's definitely a step up from GRAW2 but I had a better experience with the first GRAW. Although, it's not a big deal as there hasn't been a good Ghost Recon game since GR2 anyways. --- http://img220.imageshack.us/img220/8104/itonlydoes.gif
I don't think it feels anything like Graw either...like a whole different franchise. I'm still 50/50 on how I feel about it tho, the videos ive seen of the game and the beta I've played seems like 2 totally different games.
