Is it only me?

You are now getting old. Congratulations! Prepare for healthy eating and gray offices!
(Or just step away from the comp for a while -- it's cool -- the games will be there when you've had enough of non-computer stuff and want to get back into 'em.)

I very rarely play a game for more than four or five days before getting bored with it and never touching it again. The more I play it in that time, the less likely I am to come back to it.
