I have got a related question by the way.
Up to now I used to code the content of my crawlers (but not hardcode, it's available in xml files and can be modified, in theory that is). Now I just made a first rough version of an editor (which might be eventually publicly available although' I'm not sure anybody would use it). What do you think if I make a game with it? I feel like it's a case where it is totally an extension of my current projects and completely oustide the rules even if somebody else using it would not be.
Either way I'll make something to celebrate the event and I never checked The Bard's Tale Construction Set while always being vaguely intrigued about it so if you think it's more fair that I try to tinker something with it insted I may just do that.
