Kinda shows the silliness of that battle from Fallout 2 imo.
Not in mine.
One of the core differences between real time combat and turn based combat is that the turn based player is given full access to the situation and allowed to reflect upon it. They see what the PC would see, and they can pick from among the PC's options, then indicate (ideally the best) course of action for the PC(s) to attempt. And then the PC will execute the action to the best of
their own personal ability. This allows for characters who are far greater [or lesser!] skilled than the player is, at performing the tasks at hand.
This prevents an expert marksman character from being handicapped by a player who can't aim under pressure—or at all. This prevents nonsense like Geralt in Witcher 2 getting beat up by villagers when he's an experienced warrior accustomed to fighting trolls and mobs of lesser enemies; Geralt would know how to handle himself in a fight.... puppet Geralt swings his sword at trees and barrels until the player improves a bit—but even then they might never play with the skill that Geralt is assumed to have.
In turn based game like Fallout, it is the PC aiming the shot with the PC's on competence determining the outcome. In FO3, it player dictates the outcome for the PC; be they expert, or totally inept.
*Note that this is a core difference, but there are realtime games that afford PC skill... Like Witcher 1, and even Baldur's Gate, but the point of the differing encounter design is that the player will —never— be as informed, nor behave as comfortably as the PC. Turn based combat allows for scenes like this:
*They also tend to prevent a player pulling that off with an unskilled PC; which of course they shouldn't be able to do in RPG.
