I have two ideas for this game. They might not work with the code, but they sounded at least a little cool in my head.
1. Domesticated animals. You can domesticate boars into pigs and rams into sheep! You can farm them, control them, and use their other resources (like hides). There could also be a shepherd to watch over them. To domesticate them, you could capture a few and research domestication, and boom! Pigs and sheep!
2. You know how boars will gang up on your people? Do they only attack the person who hunted them, or your whole hunting group, or the closest person? If they can attack more than just the person who attacked them first, could they kill the bad people in alpha mission? If not, it would be very cool if they could. It would probably start as just a little hack known to few, but it would make the game much more interesting.
Thanks for reading my non-sensical ramblings!
