True, but enough of them are at this point in time that they're something a company like Bethesda would want to consider as far as market share is concerned.
Again, you are wrong. Gaming PCs are a HUGE market, and there are nearly as many Win 7 64-bit PC gaming machines (with DX 10 video cards) as there are X360s, for instance.
And again, Steam's statistics are slanted towards the hard core gamer, and only represent a portion of the total market. While their numbers certainly give an indication of the current trends, they don't tell the whole story of what's actually going on right now.
I studied statistics at Uni. All I can say is that a sample of millions of users, on the most profitable selling platform for PC gaming, is highly representative. It's a modest estimate as there are no doubt, all sorts of PCs that are not represented, that statistics like NPD cover. It's a HUGE market, with LOTs of capable gaming rigs, most of which are NOT running windows XP. (This is a FACT.)
50% of world wide computers run XP because they have no reason to upgrade their PC when all it does is check email. PC gamers upgraded LONG ago. Your argument is hinged on using ALL PC owners as the population from which to understand the PC
gaming market. This is clearly wrong. You have to look at the gaming market, from sources like valve and NPD, not to wikipedia (which was showing ALL PCs). 80% of PC owners aren't gamers! Ok, I made that last statistic up, but my point is that MOST PCs are NOT used for gaming. Developers need be concerned with the segment that are. According to the most reliable data on the subject, most gaming PCs have Win 7 64-bit + DX 10 video card with 1GB Vram.
That's freaking HUGE. It's the same size as any of the consoles seperately, even taking into account pirates who won't purchase games! :hubbahubba:
