I have mentioned PlayItHardcore.com a few times. We haven't done our Baldur's Gate HC run guide yet, which is kind of weird considering it started the whole damn thing. Basically, the guy who owns it and our main admin have both solo'd the entire Baldur's Gate series, although it starts getting incredibly difficult, WITHOUT EVER RELOADING JUST TO MAKE SOMETHING GO THEIR WAY. Loading is just because we're human and need breaks from games, or because there are a lot of game crashes and that sort of fucks up not ever reloading. I dare you to beat Baldur's Gate 1 without ever reloading. It's pretty damn hard.
Oh, and ZeroDrone: I agree to a certain extent. Items that are basically "Here, this makes this easy" ruin a lot of the fun. Beholders aren't that difficult, though. It's entirely possible to beef up your toons with spells to be immune to 90% of what they have to offer without that shield anyway.
And sorry for thinking Black Isle was the developer, because I thought Interplay was the publisher. I thought Bioware didn't formally exist yet back then.
