Do yourself a favour, play it!
An excellent, excellent game - I still have the original disks and BG is installed on my PC, because I have never managed to complete it (I'm horrendous with completing games - or not as the case may be).
In fact, I've started playing BG over the years and recently decided to play it, with the eventual aim of completing it. I've got to nearly the point where I was back in 2004, and haven't played it in a while because I got distracted by Fallout 3 and then work, professional qualifications and dating (I place an unhealthy premium on trying to sleep with Asian women above all else).
I'm taking some time off over Christmas - not to visit the family but to play SW:TOR and a few solid days of BG playing.
I love the actual detail in the game - incredibly meticulous; an excellent soundtrack with beautiful, immersive sound effects and excellent dialogue and characterisation. Plus, it's is a brutally tough game at times - especially when you're weak at the start and get ambushed by Orcs ("Spare no-one!") and/or bandits ("So I kicked in the head until he was dead"). Or run foul of the Flaming Fist ("I serve the Flaming Fist!").
Plus, tactical play in setting up your party, their positions, formation, spell-choice et al, really works.
Oh. It's bloody massive! Cue the Douglas Adam joke about the Universe.
Goddamn you, El Reg! I have 2 assignments to do - including a very overdue one that I have not even started the reading, let alone write the damn thing, and now you nudge me towards resuming my BG game!
