Travel, I'd like an around the world trip but thats probably to ambitious, just visit loads of different places.
Get a respectable job in the games industry, I'm not talking something huge, not the next Will Wright or anything, but you know, something with decent enough pay to fund the first one.
Find a long-term life partner, I'm not gonna say I want to get married because thats not the important part, I'm not ruling out the option but if I was to never have a *wedding* I don't see myself feeling any different. Plus I'd only get the stupid arbitrary term that is "civil partnership" but not I'm going off on a tangent.
Maybe one day have kids (probably through adoption) but dunno for sure.
Go sky diving, and scuba diving. Maybe not at the same time, though that would be a pretty epic dive.
Thems the big ones.
