Aha! I love so much about baldur's gate.
1. getting out of Irenicus' dungeon, thusly being able to explore Amn to my heart's content (Hate that stupid dungeon arg)
2. playing a cavalier. The joy of standing on Firkraag's slumped broken carcass is pretty sweet.
a. wielding the carsomyr
3. casting horrid wilting over and over again just after stopping time. Under improved alacrity, of course.
4. Imoen. I love imoen ;p she's adorable.
5. Minsc ~lol!
6. being female while disguised as drow. "On your knees pathetic male!"
a. watching Phaere and the matron mother die.
7. the cloak of mirrors. Holy cow! never had one item been so..so..neat.
8. the deathblows of: bodhi, irenicus, yaga-shura, sendai, abazigal, uhhh the monk (forgetting his name ;p), and finally Amelyssan the blackhearted (grrr she's an arrogant pain).
9. The treasure trove that is ~Watcher's keep. Yikes.
a. killing the 6th final guardians before heading to demogorgan. That's y'tossi (the marilleth), nalmissra (the nymph thing), the hive mother, the huntress, and the two others ;p
10. the replay value. It's priceless.
11. Aerie, and her romance. though, i'm probably the only one =b
12. lich's. I love to fight lich's!
13. Drizzt! Whooo!
a. drizzt rapid fire 5 attacks per round.
14. wand of cloudkill ~the bane of the umberhulk
15. Elves
16. the ring of Gaxx
then there is the less than desirable stuff ~_~
1. Anomen romance. ugh.
2. aerie whining, imoen torture/ imoen's qoute before final fight with irenicus (seemed less dramatic than appropriate).
3. vampires, mummies, level drain, bodhi taking your love interest.
4. Firkraag laughing at you during battle.
5. Imprisonment.
6. illithid mind drain. Sucking my brain out while i'm slashing at them. jeez..
7. social consequences of being evil. blah ;p
8. "My weapon has no effect!" Grr~!
9. "You must gather your party before venturing forth." "You must.."
10. the game ending. awwe ~_~ wish there were more.
the good outweighs the bad 
and the bad is nothing more than minor little things ^^
