I'm an artist more focused on the level design aspect of games and had an idea for a game but it would require multiple servers.
I'M NOT MAKING THIS MMO RIGHT NOW.
Just clarifying that so I don't get a bunch of people telling me not to make mmo's because they are too complicated. This post is just a thought experiment.
How would someone go about connecting multiple servers for an mmo without having load screens each time you changed servers?
To give this some imagery, imagine a game has 2 cities each on a different server and the player can go to City B from City A without any loading screens at all. He just walks there in game.
I'm not asking for how this can't be done. I'm wondering, what would be necessary to make this possible.
