I haven’t reinstalled it in some time, but I can speak to some of the matter. (Looking back, I gave it a negative Steam review in Dec 2017, after it left Early Access.)
It is a game that has had a long life of Early Access. The game has changed a lot over the years. But while some of it is the typical “this is no longer the game I liked” changes, there has also been a lot of waffling back and forth on some of the details. Some changes would seem nonsensical as well. Stages would change from being problematic in one way to being problematic in another way. It certainly didn’t help that the devs weren’t interested in fixing the camera until right before “full release”, even though the camera was the biggest problem with the stages. It was very much a development system of “two steps forward two steps back”.
It doesn’t help that some interesting content was removed from the game long ago, and never returned. Some of it wasn’t “balanced” and probably caused issues, but stuff like “headless” changed how you played (as your head was a separate object that you didn’t control) and the Christmas ornament outfits were just… Stages were also simplified in ways that sometimes made them less interesting.
There is also content that was long ago promised that seems to have fallen by the wayside. At one point there was the promise of multiple body builds that you would choose between, which was reflected in spawnable NPCs.
The “Playstation” update was controversial. It was announced that a PS4 version was being released, and all of a sudden Gang Beasts was reaching “full” release despite known issues and missing promised content. Then the update comes, and people immediately notice that many stages are now much smaller as well. (While some of the stages were legitimately too big, the new stages at times were downright tiny.)
So, overall, it is kind of… eh? Not meh, but eh. With its track record, it doesn’t really feel like the devs know what they are doing, or even what they are ultimately aiming for. Releases just seem to stagger around aimlessly.
Also, there really isn’t any single player. That’s another promise that seems to have been forgotten.
But still, it can be fun. Particularly with the right crowd. I just can’t “Recommend” it because I don’t really feel it has “earned” being recommended.
