If you do Exult, save early, save often…
Thanks for the prompt insights!
Just checked in DosBox my old Ultima Collection copy, and the earthquake sequence was OK for me — I had issues with speed, but that's OK, some INI file tweaking might be in order here.
Also, I have some trouble with Exult. V1.4 feels somehow *not right* compared to V1.2. So I think I'll give up Exult for now — V1.2 had gameplay bugs, V1.4 supposedly ironed out them, but does not feel right to me (maybe the game speed, or the unnecessary/incomplete additions -i.e. notepad-, I don't know…)
Also, I do not feel comfortable with the "save early and often" paradigm for a 100+ hours RPG…
So, it's settled then: my $6 goes to GOG now, hoping for a tailormade DosBox setup, a patched, "bugfree" game — and a proper digital manual
