The old games haven't aged well and you can't even run the originals on newer machines - your eyes will bleed out.
I strongly disagree. They have aged very well. (BG1 a bit less than BG2, but I think it was wonky back in the day too, given how BG2 promptly got rid of the wonkiness.) It's perfectly playable on modern systems and looks very nice with the widescreen mod. My eyes are yet to bleed out - 2D graphics have little problem with aging.
Plus, you already have one remake which is the Enhanced Edition by Beamdog.
That's not a remake, that's a remaster. Huge difference. It's basically the classic version with widescreen mod, some rule changes, some bugfixes, some new bugs and Beamdog's fanfiction.
