Good morning, i'm a designer, i'm currently developing a MMO with a friend.
Is our first project, he will take care of all the programming and I of all the design. But we have no experience in connections, yesterday I saw the packages that Unity handles for multiplayer, and I think the prices are high for something that I will be financing by myself, and I can not sustain an income of $ 479 per month for 50k players, I look for a server Dedicated to support at least 5k players at the same time (I understand thats called CCU no(?)), but I really do not understand how all that works. I am afraid to invest in developing the game and in the end it will not help because I will not be able to support the monthly multiplayer. I look forward to your advice of all kinds, not just connecting, it would really serve me well, and sorry for the inconvenience.
Game notes: It will be a game that will handle mostly low poly designs, but if it will have many effects, and an extensive open map, it will be zombies, therefore there will be too much action simultaneously on the screen. It will be developed in Unity. I leave some screenshots for you to have an idea, clear all the ambient light and many effects like broken things, trash, some water, etc.
