I've recently begun playing around with a tool called 'MPMPM' which lets me make modpacks for Civ V multiplayer, so I stuck together a lot of my favorite mods and now I'm totally looking for people to try the pack with. It isn't fully stable yet, I'm sure, but seems fine in single player and now I'm hunting for desynch problems and whatnot that only show up in online multiplayer games.

The current pack contains (deep breath):

It's quite a bit of stuff.

If you have Brave New World and Gods and Kings and are interested in trying it out with me (or alone; it works perfectly from the three test games I've done so far barring some minor graphical problems with canals), I stuck it up on mediafire here and installation instructions are here. You only need to worry about the Premade DLC pack section.

Tell me if you are up for trying it out and I'll add you on Steam.
