The people over at
Forgotten World are working (slowly, of course, being a fan project) on improving the graphics, fixing bugs and adding some new stuff to UIX. It's all not very advanced yet, but is very promising.
Over the years I've gotten some fun out of UIX by trying to either exploit or find workarounds to the various bugs and other quirks. I've found a way, for example, to get eight extra bags out of it (instead of the four bags you get if you follow the cheats found online), and how to keep Dermot in the cemetery in Britain (something we all tried to manage back in the days when Wayward Avatar was in business, but failed) although that trick is extremely tedious and time-consuming to pull off.
So, there's a kind of fun to be had just trying to screw with the game.
