Get a DVD player. It's not that much more and Wrath of the Lich King (upcoming expansion) could very well be using a DVD format. If you start a trial account of WoW and have Blizz ship you the install disks they actually send a single DVD, so they are making WoW DVDs already. Plus if the person wants to do any other gaming at all (they will even if they say they won't) it'll most likely take a DVD player.
