Something I stumbled across while searching the web. It is a game engine that comes with a server, then you can join your server and start making the game. You can create items, spells, classes, npc's, and map terrain. It only has 4 stats right now (Str, Def, Speed, Mag), but it is a solid engine, and it comes with a script editor. I've read that the language is similar to VB, so if you are familiar with that, you'll have a better start than me.
Right now, I'm making a game called Tales of a New World.
So far, I've got all the classes down, and 3 sets of weapons, Dual Swords, Blades, and Axes, and I also currently have 9 Misc Goods, one of which is the currency.
Unfortunately, I only have one map, since I'm mostly developing the items.
If you want to come and help out, download the Xrealms kit
http://www.newworlddynasty.com/node/8. Don't bother with the RTE fixer unless you are going to make your own Server, or unless you get Run Time Errors like crazy.
When you've extracted, go into the Xrealms folder, then go to the Client folder, and open up the client executable. Then, input the Port and IP, which are 1337 (port lol) and 192.168.1.68 (IP). Then the client will try to connect. When it does, make a New Account! The login, and create a character!
