To me, complaining about the graphics is like saying you can't get into older Final Fantasy or Mario games because of the pixel art, things don't start really looking dated to me until they started making things 3D. Like Popeye-Cloud Strife
Some old games are playable with old graphics, some are not (with a heavy dose of IMO of course). I still enjoy Might and Magic 4 through 7 even with the mid-90's graphics, but I find Daggerfall (which was "new" compared to MM7) to be basically unplayable now. Baldur's Gate is definitely on the playable end of that spectrum.
