For Rob Lang's current group challenge, I submitted . Not my first 24-hour game; I've got a couple others here, one for a challenge to make a 24-hour solitaire RPG, three for 24 challenges issued over on The Forge. Mechanically, this one is probably the closest to what I want.
I started this one at 2pm on Sunday, when my housemates took a day trip. Couldn't work while they were home, because their four-year-old and toddler both are so fascinated with me, I can't get anything done. Had to take a break around 8pm when they got home, but got back to work after 10:30pm when they went to bed. Worked all the way through about 4:30am, then got some sleep. Woke up at 8:30am, kept the door closed and pretended I was still asleep so I could finish up.
The layout is messed up, especially for the character sheet, which I just threw together instead of working out where to put things. Characters for OOF are pretty simple, so there's not much else to add to the sheet, but I might want to position labels better and rearrange things to make room for a rules summary. The main text appears to have extremely wide margins because I planned to include marginalia, but didn't have time to finish it. I plan on summarizing rules on each page in the marginalia to make them easy to find.
I'm also missing a lot of examples that I just didn't have time to finish.
