Grandpa's Farm is such a great solo game and it blew me away when I read it. I'm approaching it as a slow burn, playing the mechanics for a season out one day and then daydreaming about the results for a few days, until I write my letter.
Getting to spend time with my thoughts and the results really encourages me to savor the game and come up with unique twists and turns that I couldn't get anywhere else. Thanks brain!
The extra rules for festivals are great, and playing with other people is a delight too. I had a friend "spend a season" with me and we worked on the farm together, before they went off to start their own fixer-upper.
This game is such a great solo game that hinges on the creative aspect of letter writing, and I can't wait to start again on an orbital solar farm for my next playthrough!
