Amazon thought it could compete with Steam because it was so much larger than Valve, but Prime Gaming's former VP admits that 'gamers already had the solution to their problems'
I once playtested their MMO, I believe it was called "New World". It sucked balls. Didn't realize they were also trying to get going with game distribution.
It had a somewhat interesting combat system for an MMO, but there were a TON of glaring gameplay and balance issues that essentially guaranteed the game would be dead after a month or two.
People kept finding exploits to fuck the economy so they kept turning off trading which made it difficult to progress. I think my issue was lack of storage and you needed money to get more if I remember right. I got bogged down with inventory management and never touched it again.
