Something I’ve thought about for a while is a Wrestling Wargame (I am aware of Rumbleslam). Seeing cheap sets of wrestling figures bundled with a ring (in a roughly 1/35-1/32 zone) got those hobby cogs in my brain turning.
Plus being a big fan of the old Monsters In My Pocket Monster Wrestlers, and Wrestling in general when I was a kid, definitely pushed the nostalgia button for me.
Here’s the progress so far:
Rules will be the biggest challenge though. As stated I want this to be a Wrestling game, not a skirmish game with a wrestling theme, if you catch my drift. But interesting duelling rules are hard, and no one enjoys a melee slogging match… which is predominantly what wrestling is…
I’ll post more soon.
Let me know any thoughts.

It’s tricky for the same reason wrestling video games are never really like wrestling I assume – there’s really no way to make selling and getting heat fun
Rules wise I’m thinking
maybe each wrestler can choose from a shared list of moves and countermoves,
each move and countermove chosen secretly by each player at the start of a round but revealed simultaneously before being played out,
maybe cross referenced with wrestler stats to determine an outcome
That is roughly along the lines of what I’m thinking. Good for solo too, because you can just roll for the opponents moves, or zero player because you could roll for both.
Sorry crude english below :
Might be more work to put together, but using cards to select moves could be fun (with custom cards and signature moves only available for some characters, or maybe some characters having bonus with certains moves). I do however not have any idea about how to manage movement.
