The games I missed the first time around, such as DuckTales 2, Tales of Destiny 2...I'd replace my Chrono Trigger strategy guide (stolen from me back in 8th grade :<)
Probably would get all the RotK games I missed...
But before that, I'd pay off my credit cards and buy a house. xD I'd probably keep my job, though, I get decent healthcare through them, even if my pay isn't fabulous.
Then I'd run off to Japan, buy all the things, then go on a tour of the Disney Parks of the world...then go everywhere else I want to go.
