There is a game on Steam you may enjoy. The name eludes me this second, but you get to set a number of certain types of things to fight another of your choice. It has modding support and can be quite fun. I’ll try to find the name and edit it here

Edit: Ultimate Epic Battle Simulator 2.

I didn’t know they released a sequel. I don’t have any knowledge on it, only the first, and it has been years since I played

Edit 2: Here is the original game. It looks like it has better reviews
