I had this occur when I had country blocking of certain countries turned on on my firewall. The store runs through xsolla.com and, from memory, I had the Netherlands in my blocking/country filter. Unblocked that and the Store started working for me ingame. Source: over 1 year ago

I interpreted it this way too. https://xsolla.com/ seemed to be a platform-independent transaction/progress tracker. Source: almost 2 years ago

Companies like Xsolla exist. Pretty much any game with micro-transactions are likely using the services of such companies and are probably already tracking what you do within the game. They basically exist to increase monetization within games. Source: about 3 years ago

That being said, I worked with https://xsolla.com/ a while back. They were responding fast on support questions and are a specialized provider for gaming. You also notice that when reading up on their api (naming for example is tailored to game domain). Source: about 3 years ago

Don’t try to take on giants like Google Shopping or Shopzilla. Instead, find your niche — one that you’re already familiar with — and start small. Examples of smaller niche-centered price comparison websites are Gocdkeys that compares gaming products, Pricechecker which compares UK prices, and Farecompare that compares flight prices.
