Hi there!
So, originally I had not intended for this to wind up being a fully open game, but after some discussions, we've changed our stance on that and a friend suggested I post an ad here.

Our goal here is to try and provide and maintain a coherent DC universe. This is not a "free for all" in terms of what is available for characters and stories. Rather than year 1, we have gone with a "year 4" setting, so characters like Superman and Batman have been around, and there's some room for sidekicks/etc to be popping up without it being super weird. Some sacrifices have been made in regards to certain variations of 'legacy' characters being banned at this time and similar things.
The common point for most things is considered to be n52, but we are by no means a "pure n52" game. We've got a customized theme and setting and have decided to focus the game on three specific 'areas'. Those being Gotham, Metropolis, and Themyscira. Each location has a different 'focus' in terms of the thematic elements likely to be found there.
At Gods and Monsters MUX we want to create a world where a lot of the mystery and mythical themes to the DC Universe are still alive for our players to explore. This isn't a world where Superman has been saving the planet from "INTERGALACTIC MEGATHREATS" for decades and decades.
More info about all that, and our policies, can be found on the wiki of course!
