I am not much of a Hexen fan myself these days either and haven't been for years. Hexen is one of the best games I ever played, and would have been even more so if all hubs would have been like Shadow Wood - but there isn't really a game one plays for decades (and I started playing Hexen the year it came out).
For me, KH is not so much about Hexen as about being creative and making a game (something I became interested in about a year or two after I encountered the first computer game back in the 80s). Hexen is a good fantasy game/world to build a mod/TC upon, it's not too detailed but not too crude either, establishing a story, world and guidelines while leaving a lot of room for adding whatever we want.
Anyway, does it mean you are dropping all work on KH at the moment with no plans to pick them up in the future, or that you will spend less time on KH? I.e. would you be working with us on the Alpha and possibly the mini-beta, which could be released publicly and help us find additional team members?
Also, I didn't want to confuse anybody so I never posted much about the plans for The Serpent Power, but I have quite a detailed concept laid out for it, should I post that so you can see whether that one is something you would be interested in?
