Query: Best tactical shooter ever ... ?

Yup, could be as Ubisoft does it again.I've played through all the other Rainbow Six games numerous times and Vegas is by far the best. Without a doubt, it's the best AI I've ever seen in a game. The bad guys know how to shoot and elude you and don't always do the same thing twice when you have to repeat a section.Graphics are killer, game play is intense, sound is amazing and the weapons rule.Yeah, I liked this game ... a little.
