I've been enjoying a new round of mods recently, including def jam, questpack, virtue and d0tweak. A few things annoyed me...
Virtue: great idea, well implemented, but until you slow down how often the party comment on the current virtue, I wont reinstall it.
NPC's/summons set off traps: love this one, but it needs a couple of exceptions. In the tanner quest, when you chase him downstairs he ALWAYS sets off one of the traps by the second stairs. Doesn't make sense really.
Burglary of the bookkeeper: Um.
Smarter illusionary clones: they have a tendency to blunder toward the party, even when the group has just turned up and has no idea that there is anyone about. Is it possible to slow them down?
DEF jam- I installed the starting XP reduction along with the other options. Having later uninstalled all mods (reverting to a clean BG2 install, as advised on this very site) all new characters *still* start with low XP.
The rest is good shit though. Love it.
