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'
GoG is just the best. They don't have all the nice things Steam has, like workshop for example, but they compensate for it by actually selling you a game, not just renting it out with drm.
Lutris is just a pain compared to proton. I'm not going to say that its terrible anymore but 90% of the games that I play regularly on steam just work straight out of the box.
