PetrusOctavianus: BT2 is one of the most difficult CRPGs ever.
Kudos to the first Bard's Tale "virgin" to complete the GOG version of it.
Well partly in response to your original query, I just finished it!
I basically just said F the to-hit issues, got some speedboots and avoided most combat in Oscon's Fortress and nearly ALL combat in the last two dungeons (no magic really weirded me out with my underwhelming to-hit issues).
Some of the 'riddles' still don't make sense to me, but I managed to answer them all this time around, that is.. apart from the Death Snares. Snares 3 and 4 just don't seem reasonable at all to me. 6 and 7 have a certain kind of logic if you're willing to give them thought and a bunch of tries.
Some of them, like the Sphinx seem pretty badly designed though. The Oscon snare also leaves the order unclear, I just started trying combinations.
Overalll, I think the puzzles are legitimately challenging, there are lots of enemies worth avoiding (though it's easy to do so) but the weapon-combat is unfortunately kind of buggy in the end. I'd say Bard's Tale 1 is definitely the stronger game in the balance.
Now on to 3.
