I'm too lazy so someone else compare:

Good job vgc, you are pretty much within 5% on everything.

Keep in mind, again, that GFK goes up to the end of June, but VGC is almost to the end of August. So any games where GFK is higher are quite obviously undertracked here.

Which is pretty much everything really, apart from The Last of Us (I could correlate that game up until the end of June, and the numbers nearly matched, at least within a margin of error); Far Cry 3 (seemed spot on); Bioshock Infinite (VGC was higher but not by much, so I suspect undertracked); Luigi's Mansion 2 (same as Bioshock); Gears of War (same as Luigi & Bioshock) and Elder Scrolls (seemed spot on).

Unfortunately I can't help with where these sales are missing from multi-plats, but hopefully someone might see this and it'll lead to a little bit of DB tidying up (wishful thinking, I know).

the last of us has the highest price avarage of all the games on that list. insane. also GoW massively undertracked 

Edit : GoW:A is 160k undertracked

And I'm sure the GFK numbers don't cover all of Europe, but rather the biggest markets. So they may be even more undertracked.

Not sure if serious but... the tracking periods are different.  VGChartz are miles off on everything.

Unless you're being sarcastic, in which case, please ignore!

50 million revenue for Lat of us very good.

I'm disappointed in you, it was sarcastic. 

Seems like everything is rather UNDERTRACKED, which is nice ofcourse.
