Well but that's a bit like saying that since there are technically races in GTA it's also the most successful racing game. It will also be the most successful flying game and the most successful sailing simulator....etc etc.

I don't know, even though there is shooting in GTA I don't think I'd call it a shooter.

I agree that there is probably some other genre that would describe it better, but I think it wouldn't be unfair by any means to describe GTA as a third-person shooter.

That list is incomplete. CSGO is the most played game on Steam and is now free to play. I would not be surprised in the slightest if more people have CSGO.

interesting. Steamspy no longer works, but its last report in 2016 said it had 25 million sales (at the time it was roughly on par with minecraft sales). Since then, the concurrent player count has more than doubled, but its very difficult to get information about sales.

Wikipedia has it with 46 million owners on Steam, with the following footnote:

> Not official; the numbers were estimated following a Steam API data leak in July 2018, which gave player ownership estimates for games on the platform that have achievements.
