Well, if you want, I could keep you updated on my progress ;) I'm working together with [T]ouko, and once we think we're ready, we'll be making a thread, but in the mean time, I could keep you updated :P
It's great :D I've mapped out the first town, as you've seen :P And well, now I just came back from dinner... and I'll probably leave again in about 10 min. because friends are coming over to watch a movie :) So I haven't done anything else with it.
The houses are nearly all inserted, just need to make them usable to make maps with, and then I'm done. Only thing is though, I have little time to do that now, so I'll do it tomorrow.
If I don't muck up the houses and assuming I can fit them in... Maybe 45 minutes if I really concentrated. If I muck up, I'll try again tomorrow. If I can't fit them all, I'll let you know as of when.
