As a good contrast to a first person game, look up the sales figures for civ5.
Then you'll have something fairly balanced, as opposed to biased in the consoles favor.
Civ 5 is PC only... therefore one of the few stuff not competing.
350M PCs...
Its from that one, right?

Same source to tell that we have 1 Billion PCs active now, but ofc... the 80M consoles will have better game sells. But its probably the industry and the browser surfers who need 900M fully sized desktop PCs for. I dont know where they get those numbers but it will always stay vague so we can aswell finish with argumentation.
Here my source, ofc thats only the "startup sell", but we are now close to 10M units yet, but i dont expect it to change that much from those percentage, its hard enough to get any numbers at all. All i usualy get is "hurray we got 10M, and Steam is so successfull", but not a single word about console sells. Apparently XBox 360 was lead plattform and will get addons first.

But i hear devs complaining about PCs not being affordable to focus on... to have
the need for multisystem development. PC software, especially games, losing lot of efficiency, thats a proven condition
by me. While enthusiast tell the exactly opposite of it, i finally wish i have to power to see every single statitics and every little detail, but i simply cant, so i wont be able to understand this world anymore.
Sadly, those limited knowledge cant satisfy me, but thats probably not intended. Every attempt to show even the slightest doubts about, is setting our users into enrage mode, being attacked by mods and what else, i give up.
