I saw a post about this on r/rpg on reddit last week, fell in love with it, printed it out, and played it this past weekend with a group of friends. I ended up printing the 50x30 grid at 3 times size and taping it together. We only made it to the Ancient Age, but we had an absolute blast!
We had a group of about 6. Some were into RPGs, a couple weren't really, but there was such a fun creative energy to the table that I can't describe and everyone said they want to do it again. We ran out of steam after about 4 hours and agreed we want to play again either over multiple sessions or just make a big long day out of it sometime with some breaks in between ages. I am jazzed to try this game out with my other gaming friends soon. I've just been printing out materials and figuring out scheduling.
Thank you for making this!
