My games are in a huge CD wallet, so I'd grab that, my portable consoles since there so tiny and light (GBA Micro <3), and mainly the few things that actually mean something to me. One of those is around my neck 24/7, so I can exclude that from the 5 thing list..

1: Portable Consoles (I keep them in a bag along with the games, so it equals one carryable thing)
2: CD Wallet
3: A few personal things, like the Organiser my deceased godfather got me, stuff like that
4: My cat Gibson
5: My wallet
