Some people have gotten to the point where they hit [F5] every time they are about to talk to anyone or anything.
I'm doing that since around '87 and never regretted it. Just... back then we had to manully save. For games like these it was never different.
I also do not like Jahan and Madora much, both are a bit bland and do not really bring something interesting to the table (like... an actual character). They are better than nothing but I surely hope for the addition of more interesting NPCs to accompany you later (either from Larian or from mods).
Anyone remembers all those cool Baldurs Gate 2 NPCs modders made "back then"? I just hope the same happens for DOS.
