I'm playing BG:EE with SCS on my iPad, and I've had the same experiences. It feels like an entirely different game. Really wish I hadn't installed the "mages pre-cast spells" component though, as I think it goes too far. Was a pain to install mods on the iPad though, so I don't feel like redoing it.
The Bandit Camp, in particular, was fucking brutal. I learned to value wild mages when I had Neera successfully cast Cloudkill with a first level spell slot.
The original BG is rough around the edges (it was the first game for most of the team apparently), but it's still a damn good game. I played through it when it came out, again in late 2001, and this is my third time through. Honestly, I think that the writing is the weakest element of BG1, which improved tremendously in BG2. I'm playing with the BG1NPC mod this time, which improves the game significantly.
I also like exploring the wilderness areas; they're larges, but you move pretty quickly, and pretty much every map has something worth finding. Uncovering the fog of war is also strangely compelling. Reminds me of exploring every last square to fill in my automap in Might & Magic III - V.
