ahhhhhhhhhhhhhhhh...... monthly fee to WoW when released, says so in the FAQ : /
I knew that from the beginning. However, I'm willing to pay for a game that is decently supported, unlike D2 these days.
Also, the fee will definitely keep a decent portion of bnet kiddies off of WoW, so that makes me even happier. Most of the people I met on the Stress Test were rather cool, rather than 1337 idiots.
You may want to look into Guild Wars, Blck. No monthly fee for that one, and made by the Ex-D2 team that moved from Blizzard.
