In any game, there are decisions to be made, and there are payoffs for those decisions. In poker, you get to choose which hands you'll play, how to play them, and how much money to commit with them. Your reward for those decisions is the pot, and your potential cost is how much you've bet in the hand. By contrast, in Rock Paper Scissors (RPS), you simply decide what your next throw is going to be, and your payoff for that decision is winning or losing the throw. How much you win or lose in those games depends on what strategy you use. This is where Game Theory comes in. Game theory optimal is the strategic baseline. It is at the core of all games.
