Warframe is on the charts, yet it's F2P so shouldn't even be there. Separate category for most played F2P games would make more sense. No idea why GTA is still selling. I think a better list would simply have games RELEASED in 2018.
Really surprised to see Monster Hunter World @ 2nd! Finally getting some credit. Such an awesome game
GTA 5 is a great game and they did a very good job bringing it to pc. It has some of the best optimization and loads of features to take advantage of pc hardware. Solid story and solid gameplay which is something we sadly don't get often anymore. It puzzles me however why they wouldn't release other games like red dead redemption to pc after seeing how well gta sold.
