Even if the project is dead or not I will wrote my concept.This is my view of Lizard Town and suggestions for mod.
First one,name:Hill keep.What?Hill keep?A town named from two words isn't good.No,no,no!Let's find only one word,let's say just Keep,sounds better than hill keep.The jungle theme is okay,it works also with town name:a huge stone structure in the middle of the jungle.Some jurasic elements will be great.
Heroes Classes.One might and one magic.A lot will suggest for magic shaman,witch-doctor
voo-doo priest.Shaman is good and change fortress commander(or replace fortress).At might
let's say Assasin.
