Here is my suggestion....

I suggest that VGChartz contacts Steam/Valve and gets permission to link the user accounts here with Steams user accounts so that VGChartz can track it's users game purchases through steam much easier.  Once you buy a game through Steam, your VGChartz account would get updated.  VGChartz could offer linking to Steampowered.com's games directly from the PC games section to drive purchases to Steam to get the ability to incorporate Steams sales (of VGChartz users) and user info (Such as hours played etc of a game).  The user info would require the VGChartz user to link themselves through the profile edit page.

What do you guys think?

tried it, declined

VGChartz was declined by Valve?  Maybe the original request asked for too much info?

For some odd reason the majority of developers/publishers and other groups will not support vgchartz due to the numbers being made up. Educated guesses or not, most cannot get over that fact. I would assume valve probably has a lot of disrespect for VGChartz.

Giantbomb had no issues getting steam linking, which is kind of unfair. VGChartz is a much better community and I feel that their charts, while never to be taken very seriously provide an excellent comparison factor and should be treated the same as NPD etc.

I had an experience when using vgchartz as a reference on the atlus forums and I was banned for using it by atlusaram, the main communitymanager with something like the sales numbers of vgchartz are nothing less than completely inadequate to compare sales of our games with. and that I was providing false information about the success or no success of their titles to their community.

Giantbomb?  Really???  Well I suggest the VGChartz tries again.  If Giantbomb can get permission then there is no reason why VGChartz shouldn't.

yeah giantbomb has full integration. Including achievement support and time played etc.

That leads me to believe that maybe ioi wasn't involved with contacting steam directly and it was probably a request through Steam's forum or e-mail system which never reached Gabe or anyone with the ability to say yay or nay at Steam/Valve.

incorrect, both me and Dan were discussing it with Doug Lombardi. We have a good relationship with them. They just dont want us to know their numbers. I think integration as long as we dont track our users purchases like you suggest, we migt be able to get that.

Also your actually incorrect on who trusts us, developers dont trust our software, but our hardware numbers they have barely any issues with.

Exactly, how does VGC get its numbers? Does VGC have sources in other countries etc? And from what I've seen, VGC is always prety spot on right?

we have a decent supply of data coming from retailers around the world. We will not give out which retailers due to us being small and certain larger sales tracking companies could easily crush our ties with our sources. I know our retail sample size has increased as of late, idk at what percentage we would like to estimate our retail sample data consists of in the overall marketplace,
