I’d love like an illegal underground fighting game- y’know like the Kumite tournament in Bloodsport. Or if not illegal, something like Tekken or Mortal Kombat. Fighters from all around the globe gather for a tournament, different characters experts in different fighting disciplines.
You could have great rivalries, romances, a deeper plot behind all the fighting, a revenge saga etc. There’s great potential in this and I’d buy a well written game on something like this in a heartbeat.
