I'm trying to construct a $4 \times4$ Normal-Form Game with two players, where each player has four strategies and it satisfies:
1) The game has exactly 4 Nash Equilibria
2) All equilibria involve only pure strategies (meaning there's no mixed strategy Nash Equilibrium)
Could someone give an example of this kind of game, and explain briefly how you construct it? I'm not sure when a game has no MSNE but only the PSNE. Thanks a lot.
