I doubt Psy will want to buy any new games. He's probably saving up for a 360. As such, I'll have to be content being the only person exposed to the glory that is Final Fantasy III (*bling*) for the DS.
I know the feeling of having nothing to do for a few months. You could always start a massive project you know you'll never finish. Learn a language (programming or otherwhise), attempt to write something, or maybe tackle a huge novel.
...or, you could ensure you get it quicker through other methods.
You could steal it, but you'd be easy to identify, and I think a GameStop employee could outrun you when you're lugging a ~13 pound box around. Assuming you do succeed in your theft, each probably has a predetermined (term here), and you could be traced. You could write a bad book quickly, get it banned by the Catholic church, and reap large profits from the inevitably high sales. Mayhaps it would be possible to stake out for a PS3 in the 1 hour 20 minutes until it launches? Or, you could pull something similair to Save Toby.
you're sol and jwf.
