I sometimes draw out stuff on the pad of graph paper I bring to school (and that I never use for schoolwork). I sketch out Zelda Classic dungeons (Google it if you want to find out what it is), levels (and sometimes overworlds) for some of my earlier hacks and currently I'm drawing a Metroidish map that has a ridiculous amount of door types (15?! - but one's a door that locks behind you, and five don't regenerate their shielding) and I might make in GM if I actually learn how to do stuff like keeping weapons, having multiple rooms that you can freely access without it looking odd, etc. and has each 'screen' as one square on the pad.
Wow, I spent the most time explaining the thing I've spent the least time on. If I ever get round to it, I might just post it here.
