Yes very much so. It was my first call of duty game and has been my favorite ever since then. I even played COD 4 at a later time and still found WaW better. With the Zombies mode and the WWII setting, it was like the perfect game for me. Still wish I could play multiplayer without hackers going nuts.
I know they have a student essay for free entry, but I wish they had something for college students to gain experience with something like WWDC, where they could offer a packages like the workshops and not entry to the keynotes.
