Need user input for server concept

I wanted to start a server, but I don't want to pour all my time into a server just to find out nobody would even consider playing on it.

Here's the concept:

• 24 slot server
• Collection of 6+ minigames (some unique, some not so much)
• Every 6 minutes or so (depends on how many people are on), a new minigame is voted on and selected
• The minigame then lasts 5+ minutes (depends on the game), and then people head back to the lobby
• In the lobby, people may use points earned in games for cosmetic items

The server would basically be a collection of minigames with cosmetic prizes to spend your points on.

I would really appreciate some feedback, because I need to know if this concept needs to be changed or if it's not worth the effort to setup.

Thanks for your time,
