Control starts with a great central mystery: Why are you at this giant, ever-changing brutalist building? Who/what summoned you there? Why is this gun breathing? Almost all of these questions are barely answered and that is why this game rules. There is so much mystery that is not resolved. While that might be frustrating to some, I found it just added to the overall vibe. There is weird shit that exists in this world and you don’t get to even scratch the surface on understanding. Trust me, it’s great.
Beyond the setting, the story that is there is good and keeps you moving along. The game feels pretty great with you getting new powers at a solid clip. By the end of the game, you feel like a damn superhero. Most importantly, the main campaign does not overstay its welcome. There is some side stuff that can be a drag but it is not required to beat the game. I suggest tackling the side stuff after completing the main story.
Finally, if you can, play this game on a PC or the new consoles. I played the PS4 version and it just did not perform well. I still love it and if it is all you have then definitely play it but otherwise, play it on a beefier machine.
