a good mapper? I have been using Pro Fantasy for years, and there are some things that it does VERY WELL (Deckplans). Yet it is hard to use (CAD) and it is a pain at times. So I again started playing with Autorealm, which has been released under the GNU licence. This program does not do all, nor does it come with the kitchen sink (For that you will have to go for I don't know Pro Fantasy), but what it does, it does extremely well. Oh did I mention making symbols for a symbol library is extremely easy?
Now once I figure how to upload it, I will be hosting it on my company website, and I will also upload the symbol library I am making for the game... which is a sci fi library.
For the moment if anybody cares to give it a whirl, here you go
