- The game should have a cryptointegration, this means that the ingame currency is a cryptocoin which can be traded ingame for stuff, between players and also outside the game.
Sup mate! I still doubt about this point. it might be a "local" currency for your ingame world but it will hardly succeed outside. At least untill you will have thousands of ppl stable online most of the time. Anyway as a mature MMORPG nerd I'll try to keep an eye on your project and shitpost on your threads

Also if you will ever need any extra view from the side or anything else then just let me know.
- There would be a main world, where main story takes place, but if you continue to play, a player can own his own city, and recruit other players as his knights (guild system)
Is that something like garrisons from WoW? Like a guild garrison?
