I've revived work on this and I've opened up signups for a (super early) beta. There is still a lot of work left to go on the project, but it is mostly minor stuff (filling in faction descriptions and traits, etc). As such, I'll be releasing a closed beta to help find all of these little problems and get some feedback on the project.
Edit: We've filled up the beta, and we're pressing onward towards a release. I'll give you a firm date in a week or so, and the official release will probably be a week after that. I'll keep posting previews of the new units and factions to keep you entertained until then ;). Thanks to everyone who has stuck around since the start, the wait won't be much longer!
