Just finished NWN Hordes of the Underdark. I loaned both HOTU and SOU from dirty Bioware fanboi. I had to take long hot shower and burn my clothes... Bio germs...
Anyways, I got bored with SOU in second chapter and moved directly to HOTU and it was better. Using game engine for cut scenes worked really well and it added to the immersion factor. Too much combat, but 20+ level character can`t really do some minor quests. Also, too many puzzles. Also, main baddie had too high damage reduction. My monk with strenght 12 had to hit him alot and I really mean ALOT. Good thing I was packing over 30 full heal potions, but it really got really boring.
