WoW is on the list...More than Diablo?
You never know until it hits you...
PS Eh, okay, I know D isn't really a RPG, but you still get me, right?
Okay, WoW theoretically allows one to rp. But the Zelda's are on there.
In my order, I'd probably go with Diablo 2. And then BG and OoT to follow. I used to play OoT for hours.
