I am sincerely curious what kind of turn-based RPGs you have been playing where you dont have complete control over your actions and the combat. The only real difference between action and turn based is that in the latter things happen in a syncronous, lockstep manner. And the reason for that is to allow the player to think every action through. The outcome of the combat should be a product of your good and bad decisions. Hence why turn-based games tend to be more tactical.

Also, in my experience, turn-based RPGs tend to offer a much wider range of actions for the player to choose from. The same would probably not be feasable in an (pure) action RPG due to its real-time nature.

The quintessential turn-based game is chess. Are you telling me that you think chess does not require skill or that the players are not in control?

Fuck off, please
