<< Ultima IV & V are two of the best all time games, ever.
When this CD collection first came out, it was a very brisk seller at a premium price-it was hard to find at $50.
There is a group based in England working on a 3D public domain version of Ultima I, sounds pretty good. Don't have the URL handy, but do a google search under Ultima I. >>
Ultima V was definitely the best of the lot. It was not only right before Ultima went 3D (boooooo!!!!), but you could attack something that was at a diagonal to you! I thought being able to move the attack cursor around, rather than just hit a+up or a+left, was the greatest thing.
