WoW is the more popular of these two games. It is the obvious choice if you like PvP. PvP was an after thought in Eq2 and it is kind of clunky. EQ2 goes for more of a realistic look while WoW is kind of cartoon like. EQ2 has more features and an amazing graphics engine, but it requires a decent rig to use the better display settings. WoW may not be the game that could run on a toaster anymore but it is still less intensive on your system. They are both great MMORPGs. For now they are standard massively multi-player gaming as a whole, but I see all that changing when Everquest Next is finally released. What are your thoughts?
