I got Rainbow Six: Vegas for my 360 yesterday.  I have been a long term fan, I used to play the original Rainbow Six on my N64.  I played Rainbow Six 3 and Black Arrow on Xbox Live all the time before Halo 2 came out.  I didnt like Lockdown one bit, it wasnt a Rainbow game.  It was more like a.....Perfect Dark, 1/3 realistic, 2/3 arcade...Vegas takes the cool lvling and ranking sytem from Lockdown and takes the realism from Blackarrow, and creates a awesome game which will keep me entertained for a long time, just like Black Arrow...Me and a friend have been planning to play a old yet very fun RTS called Tzar, we are going to play this Friday..Hopefully everything will go as planned!
