They are 2 totally different game play types. MoH and BF1942 are war FPS with lots of action where RS is a tactical game that is more slow paced. It's really hard to compair the 2 in the same class.
after playin MoH for a few months and now playing RvS for my first time, i think RvS is better than MoHAA by far. THere are so many more weapons and differnt ways to eliminate ur oponent.Also as everyone else has said it does take teamwork and alot of skill to play this game, no running and gunning. its hard as hell to kill some one when ur moving cause the crosshair gets huge 2 peanuts are walking down the road and one's a salted.
