We've posted the new development page with artifacts and myths. This is the culmination of years of work on Dwarf Fortress and our other projects which never saw the light of day. We've been playing around with magic systems for years, ever since DRAGSLAY.BAS, and are looking forward to finally being able to place the dwarves into a more meaningful, mysterious and exciting universe!
We'll start in on an artifact release once the 64-bit versions are complete. We might get away with one release there, but the myth/magic dev items will almost certainly happen over multiple releases, and we won't get to everything on the first pass.
Work on the 64-bit version is ongoing. So far we have
a windows test version and
a linux test version. Here's
a 32-bit Windows version that should clean up some DLL issues. We should be almost through with Mac as well -- just need to clean up the sound library situation.
