I've been playing FO3 a lot lately and every time I talk with someone, time freezes. NPCs in the background freeze mid-step, or whatever else they may be doing. It is kind of disconcerting if I pay too close attention. FO3 is not the only game that this.
Skyrim (and other games) has dialogue where time continues during the conversation. This creates situations that are more believable, but interrupts the dialogue, thus the gameplay.
Which do you prefer? I am undecided as both have their good and bad points
