Vade Retro!

Hello ladies and gentlemen, welcome to the house of god! (Imitating House, just being sort of excited)

It's that time of year when I reinstall old classics. It's been a while since I last played BG, but it was with Trilogy and it worked fine.

Now, what I'm wondering and where I need your help is: what would you suggest to install beside Trilogy? I want something if not radical, then at least big; loads of new items and stuff. (By radical, I meant an overhaul or something.)

Whatever makes the game bigger, different, better - pick two.

Cheers and thanks in advance.
