Anybody else have Dungeon Siege? It's more of a Diablo-style game, so it's a lot less hectic and more intuitive than Starcraft, though it can still be pretty intense. I've been wanting to go multiplayer on it lately, if anyone else is interested.
Edit: Here is the page where one downloads patches for this game.
Also: Take note of the "Tool Kit" that can be downloaded from this page, which is basically a Map Editor. Now, consider what one could do with a Map Editor for a real-time multiplayer RPG...
