Thats exactly what I wanted to do. Ive always been good at sports and i miss playing and the competition, so different reasons but still, same in the end. I would think, depending on what sports are involved , you’re going to need space, physical space, soccer field or bowling alley, but even before that you need a social community page , you have to build a community of people . Then organize people into teams and create tournaments and seasons. Then compete .

Honestly , its a huge undertaking and you need to build your own “team” to execute this.

You have a product first. I would move forward to something else. Try to find the customer first , then solve their problem with whatever product last.
