Hmm. i dont see that at all. I see something else-- the accessability of the PC ADDS a flood of lower grade titles to the shelves. Take those away so they dont distract yo uand I thik the total number of AAA titles on any one paltform, PC or Console, is about the same.
Take awy from Consoles the numebr of AAA title that are ports of older PC AAA titles and I thin kthe PC proibably pulls out ahead by a tiny bit (but not a lot today. This was more true in the past.)
What I see here is that usually the range of PC games in the shelves is as big as, say PS2, but then there's also the XBOX and GC making the space occupied by consoles in the stores about 3 times as big as the PC.
This simple observation of course doesn't say anything about the actual sales numbers ...
And Id dispute the validty of adding 3 paltforms' shalf space together and comapring it to a single one (PC).
Keep in mind too that in any mature retail market, shelf space has more to do with predicted selling patterns then availability of product. The storekeep puts out what he or she expects to sell and devoets mreo space to teh ears that sell better.
That all of them are getting equal space strongly suggests that sales are more or less equal across all those platforms.
Erm, maybe I'm missing something here, but that's exactly my point.
If every platform (PC,PS2,XB,GC) get equal space, then doesn't that make the expected sales for the PC about 25% of total sales, a loss of 75% market potential?
Sure but EVERY paltform is only 25% of the expected sales. Thats your mistake.
I could as easily say that PS3 is only 25%, and that writing a PS3 game means a loss of 75% of the market possability.
Also, your leaving out Mac. If you write a Java game you get PC, Mac and Linux.
I don't knwo if Linux is measurable. But Mac is deceptive.
Mac is 5% to 10% of the market BUT its a vastly underserevd market so you are liekyl to sell a larger percentage OF that market then any of the others.
PC is equal to any of the paltforms today. PC+Mac is bigger then any of the platforms today.
Fundemtnally this is the rgeat fallacy of pie charts. They mean nothing because the oen who draws it gets to decide what pieces to cut the pie into and that makes all the difference in the story told.
