solomonhume: Honestly, BG is a good game back when it just released. It is no longer worth playing now.
Personally, I disagree.
When installing the Widescreen mod, setting the game to 800x600 so it perfectly scales 2x in 1600x1200 on a 1920x1200 monitor, combined with TWM_GUI to fix (most of) the GUI problems, BG1 is still very playable. IMHO, one should play BG1 before starting BG2, or the latter game will probably be very difficult.
If just upping the resolution one notch is not enough, you can try EasyTuTu to run the game in the bG2 engine, but to my mind, it changes gameplay way too much, gives weird weapon proficiencies, and creates the possibility to greatly overpower characters. Maybe BG:Trilogy is better in this regard, but I have never tried it.
OK, BG1 can't hold up to its spiritual successors, Dragon Age and Pillars of Eternity (the latter maybe even more so), but to say it's not worth playing anymore isn't true. That's like saying the classics (books and movies) are not worth reading or watching nowadays. A classic will stay a classic... although in the case of computer games, it may be harder to keep them running and playable in the future.
Even if they run, the graphics can and will become problematic. After 4K monitors and perfect OS upscaling take over in a few years, Vanilla BG1 in 640x480 will probably become unplayable. Maybe a 1920x1080 or 1920x1200 version, upscaled 2x on a 24 inch 3840x2400 monitor will be sharp enough, but the characters will be tiny....
