Oldhome is a solo adventure game about reuniting sky-dwelling people with their lost treasures.
The PDF is 9 pages, with clean, easy to read layout and a really nice DOS game art style cover.
A lot of what makes up Oldhome is its setting. The PDF doesn't detail it exhaustively, but you get a good snapshot of the gentle, post-apocalyptic world where cozy villages live on the backs of giant animals.
Your character is a child in a world where children come of age by doing adventurous community service for their villages. You have elected to return a treasured item to someone who passed through your village, and your quest to do so will take you across the sky to other towns.
In terms of gameplay, like other journaling rpgs, you respond to the book's prompts and write about your adventures. However, Oldhome stands out from the genre in terms of how much narrative space it gives you in between the prompts. You'll roll to generate towns and the people that live there, of course, but there's a ton of room in between those rolls (such as what happens when you travel between towns.) If you want to go nuts and write a whole novel with this system, you definitely can, and the game's mechanics really only come into play when you move on to a new town.
Overall, if you like games with bright, warm settings, and if you like solo rpgs with low-stakes adventures, you should grab a copy of Oldhome. If you don't like journaling, this is still a neat tool for building a setting, and it's worth a read.
