Decision theory vs. Game theory?

Game theory is defined (here) as follows:
"Game theory, branch of applied mathematics that provides tools for
analyzing situations in which parties, called players, make decisions
that are interdependent. "
And Decision theory is defined (here) as follows:
"Decision theory is concerned with the reasoning underlying an agent’s
choices."
Regarding to above definitions, can we say that Decision theory is a subset of Game theory? Or they are completely two different concepts? And in general, what are their common points?

I guess game theory is more about games, whereas decision theory could be me deciding whether to walk home or take the bus.

Thank you, but I think game theory is used in many different domains such as economy strategies etc (here are some of its applications: scientificamerican.com/article/what-is-game-theory-and-w) Thanks

Meanwhile, I think "deciding whether to walk home or take the bus" could be a strategy as a part of a game, isn't it? And if so, can we say that decision theory is a subset of game theory? Thanks

I've always seen the distinction as decision theory is a game against nature,while game theory is about a game against an opponent who was also making a decision. So game theory has a strategic element (If I do this, she'll do that...).

Game theory has people as players, decision theory has probability distributions of decision networks. Game theory is concerned with what the probability and utility need to be to model an observed outcome. The probabilities and utilities are sometimes modelled as piecewise functions. Decision theory uses a prior probability to predict potential outcomes. Such potential outcomes might be a Markov chain. Game Theory is mathematical, decision theory is statistical, if the distinction makes sense. There are overlaps, but that is true with everything. I do not believe that decision theory is a subset of game theory.
