Shortly after the original offer, PR boss Maceij Kuc told
Polygon the firm hoped to work with the "big four" -- PricewaterhouseCoopers, Ernst & Young, KMPG and Deloitte.
The two parties did negotiate with some auditors, but G2A claims the companies they spoke to would not allow them to publicly declare the results.
GamesIndustry.biz has reached out to these firms and the National Audit Office to enquire whether this is a standard policy, but has yet to receive a response.
The inability to disclose the details of the audit pushed G2A and Wube to seek alternative options.
"If we could not say the result of the audit, it would be of no use to us," a G2A spokesperson told us. "So we talked to Wube about it, and they agreed it didn't make sense, so that's why we agreed to openly collaborate on an audit between ourselves. It was not only provided by us but also by them. We wanted to be as transparent as possible."
Skwarczek emphasises that G2A was not aware of this limitation when it first offered an independent audit: "Our feeling was that developers would like to have this great, independent, top of the industry auditor. We were trying to anticipate what they would want. On the other side, we're open to every solution. If they say we don't need an independent auditor, we're open to that dialogue.
"We didn't know we would have to choose between an auditor and doing it publicly, but I believe [the latter] is good. I believe in transparency, and we hope people appreciate that."
G2A sellers were able to obtain keys for Factorio by abusing free giveaways and exploiting the system that sold the game direct through Wube's website
The two parties did make headway with one auditor but after long conversations over the details, G2A reports this company later said it was not able to disclose the results either.
"At this point it had been over six months with no progress, and we did not really care about the whole process, so it was up to them to determine another way to fulfill their promise," Wube's PR, community and support manager Scott Klonan tells us. "They asked if an internal audit was okay, and I said 'Yes, sure.'

"They produced quite a detailed report of the keys, who sold them, what dates and times they were sold. I thought they probably wouldn't fake it, especially since it's still over half of the keys we sent. We are satisfied with the results."
Overall, Skwarczek says the process is "something I'm genuinely proud of."
The findings still show that 61% of the illicit keys sold over the space of a couple of months were sold through G2A.
GamesIndustry.biz requested the total number of Factorio codes sold through the site to date, including those obtained legally, but G2A declined as it does not share individual games sales data.
During our interview, Skwarczek tried to present this in a broader data perspective.
"Data and facts massively confirmed what we were sure about -- that out of over 10 million transactions annually, we only have 198 [illegally obtained] keys sold through our site," he says. "That's like zero point zero zero zero something per cent. That's exactly what we wanted to prove, that this is a super safe and transparent platform."
He adds that even Amazon and eBay -- marketplaces G2A has
previously compared itself to -- have a similarly small number of issues like this, and that it's "normal in every industry."
However, he did not address the fact that more than half the illicit codes in this audit were sold through his site, nor is his calculation accurate without data on how many Factorio keys have been sold there in total.
Lack of response has frequently been an issue for G2A. To date, Factorio remains the only studio to challenge the firm's offer of 10x chargebacks, and when G2A suggested a potential keyblocker tool for developers,
only 19 companies registered interest.
Klonan acknowledges Wube's role in how G2A sellers were able to obtain codes for Factorio. These codes were purchased through the game's official website, which was previously less secure than the likes of Steam or Itch.io, although did give Wube detailed records of purchases and chargebacks it could compare with G2A's audit.
The company also offers a free Steam key with website purchases, many of which are "probably flipped on G2A", although as these are obtained legally it becomes harder to challenge these transactions.
Klonan notes that after Wube switched to using Humble's widget on its site and refraining from "giving out tons of keys for giveaways to dodgy, often fake, influencers," the fraudulent purchases "stopped completely."
"In the end, contacting G2A is treating a symptom of people stealing keys," he says. "The best way to combat that is to cut it at the source.
He adds: "For us, if the offer was not 10x the chargeback, and had some precedence setting for the rest of the game developers, I don't think we would have reached out. The amount of time it takes and administrative dealings to get this refund, it's probably not worth the monetary compensation if it was not 10x.
"G2A was helpful and we got to the end after all, but I don't think many developers will be in the same situation as us."
Time will tell whether the settlement has the positive impact on G2A's reputation that the marketplace hopes, or whether more developers will come forward in the hopes of a similar payment.
The 198 illegally obtained Factorio keys may be "zero point zero zero zero something per cent" of the site's 10 million annual transactions, but so far the only concrete conclusion is that more than half of the codes queried from a four-month period in 2016 were in fact sold through G2A.
