I didn't pop it in until about 2 in the morning (this morning) and played for about half an hour, until I realized I have to get up really early on Monday and I probably needed to sleep. I woke up at about 10 and played for about 2 more hours. Seriously, I love this game. I can't decide if they were serious when they made it, though - maybe it was my 2 A.M. logic, but it seemed ridiculous. I think the first 5 minutes are the most I've seen the word bro used at one time.
Anyway, I just wanted to sing my praise for SPM. I think I'm developing an addiction, haha.
