First priories: laptop and coin collection. My laptop because it's got my entire life on it, and my coin collection because it's worth a lot of money and is rather important to me (like mobile pieces of art engraved in metal).
Barring those two things (which I'm either leaving with or going with the house), I'd try and nab the following things in order:
- All my important folders.
- GBA and games.
- DVD collection.
- Playstation 2 and games.
- Pretty much everything else.
I live alone, so family isn't really an issue.
