This post contains spoilers for Control.
I finished Control the other day. I loved it!
The world-building and atmosphere is superb. The game was just a joy to watch the story unfurl. The characters are varied and great.
The mechanics were pretty good, and they played well. It has just enough customization so that you can pick a playstyle, but not so much that you can mess up your build, and the game becomes unplayable. I ended up using the basic pistol and Launch for most of the game.
Two cautionary notes: first, there is no difficulty setting, and some of the bosses are hard. It seems to be optional side bosses mostly, however. I don't think there were major blockers in the main line. As well, bosses tend to be difficult because they deal a lot of damage in one or two hits. So you have to get good at avoiding taking hits. A fight which is going well can go south quite quickly.
Second, the game is clearly setting up for an expansion, DLC, or sequel. The ending, while tying up the main story and seeing Jesse grow into her position, leaves several important threads dangling. Honestly, though, I'm really looking forward to any new story content.
Control is a great game, and I highly recommend it!
