I always attempt this in every game with animal interactions. There was a really cute minecraft server I was on for a while that provided plant-based alternate recipes for everything. I really like Oxygen Not Included but the nature of the player's relationship with the "critters" grinds on me the whole time.
I've given thought to this one as a vegan in the game industry. It's strange. I'm happy to play games like Cyberpunk and murder just about everyone in my way. But when it comes to cozy games, there's something discordant about the "build a happy little farm" vibe and "kill all the fish you want". It just doesn't match the fantasy cottagecore games are selling for me. :shrug:
