If you are playing an MMORPG, your time is worthless. They are all insane time-sinks. Even a casual-friendly game like WoW where you can "just log in and out for short sessions" realistically takes close to an hour or so just to log in, check and relist auctions, do a couple of daily quests, mail off new loot to your mule, and say hi to friends. And that's just the daily-chore part of playing.
