I have the xbox version but I can't be bothered to play it. I hope they don't mess up the Rainbow series in a similar fashion.
They already did ruin Rainbow Six. Go look at the trailers for Rainbow Six: Lockdown.
GR2 on the Xbox is still good old Ghost Recon. The only thing it's missing is the map and two fireteams. Yes, to a lot of people those are extremely important things. Sorry. For the rest of us, it took a game that was a lot of fun but also extremely frustrating and made it far easier to get into, and removed 90% of the frustration.
I've been playing GR2 on Xbox Live with a good group every monday and it's been a blast running through missions in co-op.
