Why are you unable to cope with the success of this game? Why does seeing mere images of this game induce so much seethe in your body?
Dude, it's clearly just a quickly made asset flip to give people what they desperately wanted with ER. An experience that is built with co-op in mind. You should be fucking happy that they quickly put this together and didn't put in so much effort. This means they can go back to actually making the games you want and putting in more effort in that.
Understand that not every game has to be made for friendless, anti-social, hopeless fucking losers like yourself. There's plenty of other shit for you to play while waiting for the next FS single player game.
It's a massive success and you WILL seethe, you WILL cope, and you WILL dilate.
