While this sounds fun, here are my concerns:
- this is a fairly script heavy thing for such a small trival feature.
- This feauture will also not have many slots due to it impacting the game too much when there are more than 3-5 players.
if anything, especially for Tanoa, why not add a new faction? Make it a local tribe faction, rather than cannibals. The local tribe faction will have certain perks that will give boosts to a specific, possibly chosen thing. It will also be relatively script heavy but it will not focus entirely on cannibalism. This opens up for more possibilities.
