Those were the most popular game on Steam when grabbed them. There are no similar games on the top to compare Destiny number to. I did compare it to D1 but of course you ignored that. What game would you compare it with? Is there a lot of sci-fi fps games with open world co-op out there? There's nothing out there like Destiny as a whole. I guess you'ld like to compare it to brand new games, Anthem? Division 2? Neither of those are anything like Destiny except yiu shoot things and there is loot. There is absolutely no way to yell how many people bought the season pass.
