So I've been playing pretty much nothing but TF2 and WoW for around 4 months now and want a change of pace. But I see at least 3 versions of HCE that are active, and I'm not quite sure whether or not to fully update.

So, my questions (Addressed to the individuals of Modacity, not Modacity as a whole [If that makes sense]) are:
What version of HCE are you using?
What version do you think is most active?
Which version has the most peripheral support?
And finally, what custom maps are being played now, if any?
