I believe this should be an alternative mode. Many people have played games like Strat, DMB, APBA, and Dynasty. It's an untapped market.

Like I said, send me a private message to learn more.

We use StatsPlus and Discord to help manage things. We currently have 20 teams but will be expanding by four more teams at the end of the current season.
