Your opinion on a PvP blockchain space game I'm developing

Hi,

So, the point of the game is to conquer the most amount of planets possible, and I'm thinking of the following:

  • Enforcing the players to assign themselves an in-game name, it is more fun to see planet X is owned by "noobPwner69" than an address.
  • Making this name creation payable if wanted to be done more than a second time (very small fee, $1), to promote people sticking with their names.

Am I wrong to enforce names, and/ or ask for a fee? What do you guys think?

Thanks!!!
