[quote name='Mojimbo']How much does the World of Warcraft software cost at retail before you get the privilege of paying $15/month to Blizzard, Rocko?[/QUOTE]
$30 for the main game, the first expansion, a free month, and two strat guides (that are sort of useless).
I figure, if I play it and enjoy it for at least a half hour a day, that's ~15 hours for $15, or 60 hours for $60, which is more enjoyment to my dollar than your average $60 360 game. Not to mention I haven't payed a single dollar out of pocket yet since I have tons of GS credit from the Movie Gallery/Hollywood Video deal.
