I am currently playing through Baldur's Gate (PC). It took a bit of time to adjust to the old school resolution of 640 x 480 but once acclimatised it's still a quality game. I know there are programs such as EasyTutu and BG Trilogy that improve the engine and the resolution, but after trying them I reverted back to the original install as a matter of preference. Both altered the experience a little too much for me, and not always in a good way.
I have my GPU scale the image to 640 x 480 otherwise the display scales (stretches) it to fit my 1920 x 1080 screen. The latter distorts the image a little too much. The former suits just fine with black bars either side.
If this Enhanced Edition comes out soon, I would be interested. I'm not too far into this playthrough, so if this arrives in a timely fashion and doesn't distort the original experience too much outside of modern resolution support and an updated engine, then we'd be onto something.
