Man, I'm telling you.... This XRGB2 thing is absolutely amazing. At first, I didn't think it would really come in that handy, but after finally seeing the Saturn hooked up to it, on a large Sony HDTV, I can definitely say that the Saturn is a dream when combined with one of those babies.
First game I tried was Sega Rally Championship, and it looked so clear and clean. Then I tried Daytona. Wow. The colors for all the cars going around the track are very vibrant and detailed. So far, of all the systems I've tried with the XRGB2+, I would say that the Saturn has clearly been the best so far, and the SNES the worst. (the SNES doesn't look right on the XRGB2+ for some reason, at least with mine).
Man, the Saturn truly looks amazing on any VGA device with this thing. But the really nice thing is being able to hook it up to a nice modern day HDTV, and to get a nearly RGB picture on a huge screen. The improvement over S-Video is considerable.
