dtgreene: I believe that the Tutu and Trilogy mods for the classic editions allow you to import characters from Baldur's Gate 2 and its expansion. This would, for example, allow you to transfer a Fighter with Greater Deathblow into BG1.
Deathblow and Greater Deathblow are often considered useless, because they don't work on enemies higher than a certain level, but they totally break BG1; the fact that everything is lower level allows you to kill pretty much anything with these skills.
(Interestingly, some of the HLAs are reasonably balanced (or are at least semi-balanced) if hacked onto lower level characters, but Deathblow is not one of them.)
Yeah I still play Tutu on my XP rig and still get the impression that this is much better than the BG:EE editions (I can make a half-orc Blackguard in BG tutu for example but can only recruit Dorn in BGEE, which makes no sense at all. Can half-orcs become Paladins(Blackguards) or not?!
The only reasons I grabbed the EE games was because of the huge bundle discount GOG offered last year during that huge sale) and was curious about the new content.
