NFT Game possible token creation

Job ID: 32238015

Budget: $250 – $750 USD

Good day, i am an NFT Creator who has created and minted a NFT project of 2d characters.

my goal is to have a 2-d platformer game where users can connect their NFT's and fight them against one another

i want 4 game modes

-single player (fight vs cpu,every 6 fights is a boss battle)
-Battle Arena (free for all with a handful of users)
-multiplayer no stakes (Fight PvP no gambling involved)
-Multiplayer High stakes (Fight PvP user can bet)

not sure if it makes more sense to create my own token for in game betting and in game rewards or just to use an already established token -- this is something ill need help deciding
