TL;DR: This is the definitive RPG, and my most favorite game. Ever. Buy it now.

Story: 5/5
You are the mortal progeny of Bhaal, the deceased god of Murder. I think you can assume awesomeness will follow.

Characters: 5/5
Memorable characters abound here. From Minsc (and Boo) the loveable fool of a Ranger desperate to do good in the world, to Viconia the damaged Drow desperately trying to survive in the overworld.
CHARACTERS CAN DIE PERMANANTLY. SAVE OFTEN.

Romance: 4/5
If you're a playing a female, there's not much variety. That being said, male characters can romance Viconia, Jaheira, and Aerie (and.....Neera). All of the Romances have depth and feel meaningful. It isn't give a gift, get laid, romance over.

Combat: 5/5
Strategic use of spells, abilities, and careful planning will be your only saving grace. This is a difficult game. I suppose it's a mix of real time strategy and action rpgs.
REMEMBER, THIS GAME IS F**KING HARD. DON'T B**CH ABOUT IT ON THE FORUMS!!!

Gameplay: 5/5
Absolutely solid. No nonsense. The EE ironed out any bugs (so far as I've encountered) with dialogue. You should'nt encounter any bugs or glitches, definatly not any game-breaking ones.

Music: 5/5
Perfect in every way. Works for every situation, nothing feels out of place or silly.
And that opening is just sweet! BUHBUH BUNBUN BAHBAH

My most favorite game ever, now updated, and with better multiplayer.
F**k yeah I bought this.
