Middlecrest is still an ongoing project. It's been stagnant for a few years because life got in the way (it has a way of doing that). It's been a combination of busy employment, health-related issues, and technical hurdles to overcome. All have conspired to essentially halt most progress.
There is no definite timeline for updates mostly due to health and work schedule. Currently I'm working through re-coding some of the basic world generation routines. I'm aiming for end of April to have world generation and a small demo posted. So, stay tuned!
In other news, apparently I was the last one to hear that Dice Holdings Inc. acquired Sourceforge back in 2012 (consequently, around the time progress halted on Middlecrest heh) and has made some skeezy changes to the operation of the site. I have recently been converting over to GitHub (links to follow soon) but, with all my other projects going, that is taking a little bit of time.
