Like Tixi said, there’s no reason to write off MG Horde - in fact I question why didn’t immediately look right here! You asked for community, so one must ask, what exactly do you mean by that?
- population size?
- or atmosphere?
MG Horde is not so different from MG Alliance if you’re looking for the latter. If it’s population and crowded streets you’re after, then you’re stuck with the drama of WrA.
But if you’re looking for somewhere that is friendly, mature, and most people keen to RP then MG Horde is a solid place to try!
We even have our own community to welcome people that are new to the server and looking to meet people, find guilds, and get involved in our RP events. See forum thread here:
