I preferred BG 1 + Addon, played it 3x - BG 2 + Addon only 2x. I like RPG without love stories. Imoen was cheekier, more alive in BG1 than in 2. I missed Khalid and Dynaheir in BG 2 <img src="/ubbthreads/images/graemlins/puppyeyes.gif" alt="" /> - so my troop was not nearly the same as in BG 1. As I had developed strong emotions for my little troop in BG 1, I had a greater distance to those in BG 2.
Guess, this was my problem: too high attachment to my chars in the first game. Kiya
