rainbow six series offers tactical approaches to hostile situation. rushing in and mtv like killing sprees will be punished. but step by step, tactical teamplay will lead to success. i like that.
though i have to admit that since they focus on consoles too much, the gameplay gets lower and less intense. the porting to the pc aint that good anymore.
i cant count the hours of fun i had in mp lan battles in Rainbow Six Rogue Spear and co.
big minus point: way too short
big plus point: if you release a new version every 2 weeks that doesnt matter anymore
cheers
