I like to see how the game feels with default keys.

If I hate it, I rebind.

Or sometimes it's how the key is pressed. I gotta sit there and hold the button to open every single thing as I'm searching through a house or whatever? Yeah, no thanks. Can I rebind that to just a single click?

If I can't rebind, I find a way to deal with it. If the gameplay itself becomes boring because of key binds/how it makes you interact with the world, maybe the game isn't very good.
