Polish key reseller G2A has published a detailed breakdown and defence of how it operates as a business amid renewed criticism from game developers and publishers.

Last week, the founder of indie publisher No More Robots Mike Rose took the key marketplace to task for having seemingly unblockable ads appear when people searched for certain game on Google - Rage Squid's Descenders which Rose's label published being the example given - something that G2A insists is an error with Google.

This escalated to him and other indie developers and publishers saying they'd rather people pirated their titles than buy them from G2A before Rose called for indie games to be pulled from the storefront altogether.

In a post on its website, G2A has tried to downplay the impact that it has on smaller companies, saying that only eight per cent of the roughly one million game sales each month on its platform are indie titles - around 80,000. The firm also pointed out that there were just five listings for Descenders on the marketplace at the time of writing.

Once again, G2A compared itself to other third-party marketplaces like Ebay and Amazon, saying that its role is to ensure that buyers can buy and sellers can sell on its platform while also ensuring it knows who everyone involved in the process is.

"The role of our platform is to make sure that buyers and sellers have a safe and convenient way of exchanging goods for money," the company wrote.

"If you go and sell a bike on eBay, they don’t check if you actually have that bike in your home. They can’t check if the bike is working, if the colour is right, etc. What the platform checks is who you are, meaning it gathers your personal data and payment information, which, if need be, can be given to proper authorities. It also provides a system that allows people who buy a bike from you to rate the transaction. A good marketplace also guarantees a successful purchase and offers its buyers a refund if something goes wrong – for free, of course. And so does G2A with its Money-Back Guarantee."

The company also addressed concerns of people using stolen credit cards to buy keys in large quantities from publishers and developers with those who own the cards eventually getting their money back while game makers were left out of pocket. G2A says that this is very hard to actually pull off, explaining that only one per cent of transactions on its platform are "problematic in any way."

So confident is G2A in the fact that developers and publishers aren't losing a large amount of money to this kind of fraud that it has vowed to compensate companies that lose out to credit card fraud ten times the amount they're out of pocket via a third-party auditing company. The first three audits for claims from a developer or publisher are on G2A; after that the cost is evenly split.
