That game...utterly...sucks. I hate it. And not just one part of it. EVERY aspect. Gameplay = crappy. Sounds = crappy. Movement = crappy. Graphics = lame. They aren't poor quality or anything, they just are not nice. GRAW was better, but also sucked.
Operation Flashpoint: Dragon Rising is epic. Singleplayer AND multiplayer. If you get hit in the arm, you get innaccurate. And you start bleeding. If you don't stop the bleeding by using a medkit, then you will die. And only Medics can heal you all the way. Gameplay is awesomeness x9999999999999. it is one of the few games that I can sit and play hours on end, where I can redo missions no matter how hard it is or how often I die. Multiplayer is also epic...
Dragon Age: Origins is almost epic. Great RPG. Decent graphics. One thing that keeps it from being epic is the amount of blood and how you get covered in it, its kinda dumb after a while.
Fallout 3 is also almost epic. Great gameplay, lots of mods...the main thing that holds it back is that it takes forEVER to get from on place to another...it needs vehicles of sorts...I mean, everyone figured out how to make lazer guns, rocket launchers and what not, so...
Rainbow Six: Vegas 2 is epic. I've beaten it several times, and played it a lot. Multuplayer rocks as well
WoW is a great game even if its not epic.
