as far as game systems go, i've always thought of dreamcast as being the system i'd have if i could only choose one. with all the emulation possibilities, ability to play burned games, and alter your general state of being it seems like the perfect choice. but in more practical sense (i don't need to play THAT many games) i might have to choose the ds. since it's got a port of link to the past (my favorite game of all time) it's practically a shoe-in.
non-video games aside, i'd bring my tape walkman since it's got a built-in speaker and microphone. that's aside from clothes and hygiene items, mind you.
what would you bring?
