It's open world game with interactivity and customization. You can't say that at all
He sure can. There are tons of modern open world games which aren't riddled with bugs and performance issues (assuming they're not developed by Ubisoft, at least). Being open world isn't an excuse to release a low quality product anymore.
I'm really not the person to be complaining about graphics, especially when it's an open world game and not a corridor shooter, but I'm stunned to see Bethesda not being able to avoid performance issues with the current state of visuals. The game reeks of a rush job, it's either that or they're just incompetent.
