Or just rent it..
I rented it and didn't even play it before taking it back, played some PC games instead. Had a free game rental, picked it up for purely "academic" purposes-surely one wouldn't want to be caught discussing modern game desgin elements without having played the Greatest Game Ever! Heck, maybe the game would even not totally suck ass.
Then I looked at the rental on the coffee table every once and awhile for a week and played bearded men spreadsheet games and Quake Wars on my PC instead.
