so... i hear that everyone loves this game, etc. i've never been in to gaming, but enjoyed the occasional round of warcraft III. i've got a new iMac 20inch Rev B, and i think i'd like to get in to World of Warcraft... but i have a few questions... 1. will it run well on the computer? 2. is it like warcraft III, or do i only command a single person through levels- like diablo? 3. do i have to play online? or can i just play on my own? does that mean i have to pay a monthly fee to play the game? newbie questions i'm sure... thanks for the help!
