At the moment, no.
But when I was playing this text-based MMORPG a few years ago, I was just so addicted.
I couldn't think of anything else then, and it was really hard to study good.
At the end of the year, just before the exams, I realized it was going to be a close call. At that point I just quit the MMORPG. It was way too addicting, and I wouldn't do the year over just because of a crappy stupid game!
Best decision I ever made!
