This looks so COOL!!! Back then I never had Ultima, but I did play a trilogy of similar games called EXILE. It has nothing to do with the Genesis game of the same name. The first of the trilogy was called Escape From The Pit. That's about all I can remember from it. That and you could customize a bunch of party members and have any class you want, at the cost of food and gold. Thieves could pick door locks, clerics could heal, ect. It would shift day to night and visibility would shrink when it got dark. You could keep finding more food lying around like Castlevania to keep going, but unlike Castlevania it was required or else you'd go hungry and die. Enemies would also seem to randomly attack you on the overworld, but you could be attacked in the villages too. For instance, you could attack someone and have knights chase you down. You could also talk to literally everyone in the game to get every little piece of information, even name and background. It was an INSANE amount of detail.
