Roommates and My XBox/College and DA

So my roommate just got "Sleeping Dogs" for the Xbox.  Since I'm the only one of us six who bothered to bring their Xbox up here, he's using mine.  I have no problem with my roommates using my stuff (just don't touch my computer.  It has my entire LIFE riding on it, almost literally).
When I went to sleep Sunday night, he was playing it since he just got it.

I woke up the following morning and he was still playing it.
That's perfectly normal.  It's a good game, so I can understand playing it for 24 hours straight.  I've done that before.

I wake up this morning, and he's still playing it.
That seems like a little bit too much of any game at one time.

He's played it for about two and a half days straight now, minus about three hours' worth of classes.

C'mon, man!  I have camos to unlock in MGS!  I still have cases to solve in LA Noire!  I still have to finish pimping out Connor's estate in Assassin's Creed!  I still have to beat Arkham City!  I still haven't played all the New Vegas DLC!  I still have to finish watching Firefly on Netflix!
Most of all, I NEED AN EXCUSE NOT TO DO ALL THIS HOMEWORK.

****

Oh, yeah.  I went on a week-long Artist-spree, if you haven't noticed.  I've spent most of the past week sketching, coloring, and uploading.  Expect yet another hiatus from me, though (If any of you out there care).  I'm starting to pay for the lack of homework I got done over that week.

I swear, someone needs to shut down DA and hide my sketchbook for the two and a half weeks left in the semester...
