My biggest abiding memory of playing bg I and II is fighting the pathfinding. I didn't play the enhanced edition, admittedly, but I will never forget how annoying it was to hear "you must gather your party before venturing forth" in towns, cities, and forts while trying to gather my party.
The other one was how annoying it was to have encounters sprung on me when I was not strong enough to handle them yet so I had to have a specialist for dealing with the most annoying of these sncounters (a ranger with the problematic encounter as a favored enemy as my main character). Remember, in rt combat situations I get tunnel vision and pausing can only help so much. I refused to turn down the difficulty as well, due to the fact that doing so reduced xp gains and I feared not having enough levels for later encounters.
