I get asked this question a lot. Lately it’s been the number question of perspective 3DGameStudio buyers.
Massively Multiplayer Persistent Online Role-Playing Games (or MMPORPG) like Everquest are a huge undertaking (much more complex then a simple “death match”) but they are very much the future of online gaming.
The Professional version of 3DGameStudio supports client/server based networking using the DirectPlay architecture. Using TCP you can set up a server on a single machine which stores and updates your game world. Clients can connect to this server and send it messages (movement updates, commands, etc). The server then updates the world and sends the updated information back to the clients.
I’m currently working on a multiplayer workshop (like the Flight Sim and Venture workshops that have already been released). In it I will cover the basics of multiplayer gaming with 3DGameStudio. Where you go from there is up to you.
