What a weird game.
Everything is so unimpressive and yet, I've played it for three hours straight just now.
Combat is already repetitive and your moves lack meaningful impact, clearing outposts (which seems to be part of the main quest) plays out the same every time, the dark-light-moral-system seems to be useless and the characters are all forgettable.
And yet...I couldn't stop playing for a while Looted stuff, did some quests, cleared some outposts for gang wars, explored a bit. It's nothing special but I enjoyed it.
It's a simple game that works well to wind down after a day of work.
So...yeah...that's where I'm at with Biomutant.
