For a normal-form game G and a player i, can removing actions from player i yield a better Nash equilibrium *for i*?
Has this been investigated?

@niplav it seems trivially true that there are cases where this applies, but I don't think you can make a strong statement about how to get more general or specific than saying "sometimes, yes."
By contrast, it seems like coordination between players is like the Swiss Army Knife of game theory.
