A new MMO comes out. You've read the reviews, Watched the promo videos. Changed your desktop to show the buxom model on their cover art. Subscribed to the newsletter. Read all the developer interviews. Attended the chats! Participated in the lively banter between the lead designer and the people of a well known community forum! You've made your own guild before you even got to play the game! You pre-ordered the special collector's edition, and the game's theme music is on continual repeat on your iPod!
The fateful day comes, you install the game and ... well, it's a decent enough game, but it just isn't what you expected. You play it for a few days, and then start wishing you hadn't given away all your gold and sharded your epics in your old game. And maybe you suddenly regret telling the raid leader just exactly, precisely what you thought of him. So do you stick with the new game? Or return to the old? How long do you give a new game to grab you before you erase it from your hard drive, put the disks on the shelf, and call it a decent effort but just not the game you wanted to play? Just the free month? Until you reach the max level? Or just fifteen minutes perhaps?
