Yeah, I found the SimGirl forum once and saw that some people were redoing it. From what I can tell, though, they had the typical short burst of work done followed by a much longer period of stagnation; hopefully they can get past the hump and actually follow through.
As for SimBro2, well, what all these things require is a truly dedicated programmer. He doesn't necessarily have to do all the work, but there has to be one person who steps up and consistently gets things done and stays on track - WM has necno, SM2 has cmacleod42, most of the original 'greats' were done by pooolka. This applies to all amatuer games and mods as well; teams may be nice in theory, but when it comes down to it there has to be one definate leader to keep the ball rolling.
Oh, and good job, Dagoth. Very nice. Sad that no one ever did anything else with that source, though; I still think HHS had lots of potential.
