I like the concept, but it's not a great implementation.
-Not being able to interact with other clans is a MAJOR downside because RNG determines if you'll be able to do anything at negotiations. Clans will just randomly decide to war with you in the first season, which in turn makes others not want to form alliances with you, and snowballs further until they start to accept peace offerings.
-The game kinda corners you immediately by making the only person who can hunt for raw meat be unable to teach that skill to others.
-I'm sure that's all a pain in the future, but I wouldn't know because my files keep soft-locking. The first time, the only child I had turned sickly green after a healing session and became unable to interact with. She didn't age either, and remained on screen even when I exited to the menu, until I deleted the file. I tried again and managed to make it past the marriage of my first child, but the season changed and suddenly everyone was unable to be used or viewed again. I don't know why that's a persistent problem that occurs when time passes, but it's a big deal for the game to just stop letting me play.
