Love the multiplayer. Thought the single-player was just so-so at best. Kinda easy no matter what skill level you set it at.
For more raw battle type WWII action (but not overly cumbersome to the point of being annoying like some game) you might also try Medal of Honor: Allied Assault. I downloaded the demo to that one last night and was floored. I've heard the multiplayer sucks though, but I can use RTCW for mulitplayer. If you're interested you can pick up Medal of Honor for $17.99 plus shipping (thread in HotDeals forum.)
