Well, I'd approach it the same way that I approach every other MMORPG
that hits the market... play the beta, get a 'friend code' if offered,
or if it has compelling reviews I might just pick up a copy of the
software and play for a month. I still play CoH and CoV, with Guild
Wars for fun on the side ( Factions is da w00t!

), but wouldn't be
adverse to playing a WW MMORPG as well...
The conditions being, of course, that it has a compelling storyline,
setting, interface, character design and at least passable graphics.
Oh, and that they drop oWoD completely. That game's over.
