Just a small result of one evening of not very hard work... As an example of how I would started changing ADoM if I would be allowed. Here, just unpack and load the only saved character, and explore nearby villages, temple, your own house etc. Most interesting things are hidden in new variant of Laven, also it worth to get druid's quest. Surely, you'll have some fun 8).
If you'll like it - I suggest to organize a small competition in modifying the game by this way. May be, the Creator will like it, too - at least, I hope...

With best regards, Mikhail.
