I was thinking of putting together a handheld counterpart to my console comparisons, but first I have a few questions.
Besides Nintendo, and the recent PSP, I have no clue as to other handhelds that have appeared on the market. Also, I can't look up sales data for any of these anyway. I'm not really sure if it'll matter to much, since it's possible none of them sold enough units to really justify having them in the comparison.
Also, why is the GameBoy and GameBoy Color seem to be combined? According to wikipedia, the GameBoy Color had increase specs in many areas, and since the two were released nearly 10 years apart, I couldn't see how the Color version couldn't be somewhat updated. Why then, are sales for each always combined? I haven't done a lot of research yet, so I can't say it's not easy to find, but does anyone know the separated sales, not combined?
I'm mostly interested in looking at sales trends and market changes. This is mostly because the Japanese market has been stagnant in the console market, even shrinking a little the last generation, and I would like to compare it to the handheld market, to see if the handheld market in Japan is growing. This could lead to the point that handheld sales do compete with console sales. Or it might just show that the Japanese work too much.
Either way, it'll be a valueable addition to my comparisons, and so any help in different handhelds from the past 20 years and it's sales, or links to sources, would be much appreciated.
