Honestly wild they would close Tango, of all developers, after they delivered maybe Xbox's only coveted exclusive (though it has since gone multi-platform). Redfall and Starfield were both duds, and I'm not sure if Xbox has had any other exclusives at all (coveted or otherwise).
Having said that, it's pretty bad that Xbox is closing these studios regardless of if they have put out a hit recently or not. As Arkane Lyon chief Dinga Bakaba points out:
You say we make you proud when we make a good game. Make us proud when times are tough. We know you can, we seen it before.
Microsoft certainly has the money that they don't need to be making these cuts. This is clearly the result of Line-Go-Up syndrome, and will only hurt them in the long run.
PlayStation is already eating Xbox's lunch since Xbox has no console selling exclusives. How are they going to make any good exclusives after cutting so much of their staff? (Also as a side note, I find it wild how much Microsoft spent on Bethesda just to cut so many of those studios.)
Overall, a cruel and short-sighted move from Microsoft.
