It's already been done (sorta)(also not a h game so don't worry about clicking the link)An H game where all the girls are brands, titled "Screw Capitalism"
Yeah but that was made by KFC and only one character is a mascot. I'm talking like full on personifications of Best Buy, Trader Joe's, and Home Depot
This sounds like a game about cancercompetitive conway’s game of life. each player has a designated starting area to arrange cells in whatever pattern they choose. cells are a different color depending on what player started with them (when everything on the board is a stagnant pattern, whoever has more cells of their color wins). enemy cells could be either “converted” if they stay alive and are surrounded by more allied cells than enemy ones, or just killed and replaced later by an allied cell, both functionalities could work
if you want to have a lot of fun (and suffering getting it to compile) you could give the players massive starting areas and try to make a neural network get good at the game. computer battle!!!!!!!!
