Rather than use the top10, I'd recommened total software sold (by 3rd parties).
Total SW sold (VGChartz numbers, they are proven to be a bit low on both Wii and X360)
Wii: 297M
X360: 228M
Ps3: 132M
Rough estimate of sold by 1st party:
Wii: 160M
X360: 50M
Ps3: 30M
Total by 3rd party:
Wii: ~ 140M
X360: ~ 180M
Ps3: ~ 100M
When I write Fact: in one part of the post, and opinion: (or a similar word), it's not because I can then say "my opinion can't be wrong". It is to inform what part is pure facts, and which part I try to draw a conclusion in.
