Rainbow Six Vegas is more of an arcadey game(Health regeneration, no more one hit kill) compared to the true spirit of Rainbow Six. (Tactical map plannings, outfits for respective members)
Its not a bad game and its fun as an action game by its own right with a cover system that is arguebly better implemented than Gears of War.
HOWEVER.
Their blasphemous behavior of providing TERRIBLE, HORRENDOUS, SHAMEFUL support with HALF-HEARTED implementation for multiplayer options and interface for the PC port is something I find it IMPOSSIBLE to forgive.
Grrr, I'm still so pissed.
