I think he meant in terms of graphics and such.
And it is pretty amazing as far as how quickly computer technology has advanced in the last 20 years.
I mean, play Wasteland. It makes Fallout 1 and 2 seem really advanced graphics/technology wise. Then play Fallout 3 and New Vegas, which seem really advanced graphics/technology wise compared to Fallout 1 and 2. In ten years, 3 and New Vegas will seem just as "old fashioned" graphics wise as Fallout 1 and 2 do today.
