Played BG2 a lot, back in the day, including TOB of course. Couldn't really stomach BG1, never fancied save-scumming due to one-shot kills. Wrote my own character' AI scripts, mostly for adaptive melee/ranged switching.
Even participated, briefly, in a small but very ambitious BG2 mod project (not really a mod, more like custom campaign on BG2 binaries), created a script editor IDE (with compiler integration and syntax highlight, no less!) and made custom location maps, using those awkward community-developed tools (now, that was a bloody challenge). Only, that was 20 years ago.
Eventually I was able to upgrade my PC so that it could run NWN, moved on and never looked back.
It's a great game, the storytelling and immersion are still top-notch, even though the rest of it didn't age exactly well. But, I can only playing through the same story so much. Plus, RTwP isn't my cup of tea in the slightest.
