I found this online MMA management sim game. Basically u create and manage up to 10 MMA fighters. You deal with their sponsorships, training, booking fights etc.
Its free to play although theres the option to purchase a VIP membership which opens the game up loads and allows u to run companies (gyms, nutrition company, clothing company, fight orgs).
If anyone has a go, I'd advise creating a fighter in Hilo as its a new city on the game so the gyms are quieter (smaller class size means better fighter development).
Anyone can join my gym, Wolfslair Hilo. I'll also advise u on how to create good fighters and what sort of training schedule to look at.
