How big is your budget for this project? Do you want to incorporate Crypto currencies into the game as a currency or are you going to create a new Alt coin or third party token for the game?
I have no budget. Spend two years writing a code. I know JavaScript and to be more specific I'm using image animation cartoon engine to write a game code. This engine using API keys. The engine is licensed and copywrited.
Soon I will upload a demo.
I have an update:
Almost done with the map editor, which will help to build any map and any object on the map. The game map is isometric for 2D games. The size of the map from now on can be any. The map is built of tiles and loads only those that can be seen from the screen. I think this is a huge step forward at the moment.
The game will be a copy of Open TTD, but with the different scenario and online. Not sure what can be better to use someone else currency or create its own.
