TSA writes: “The immersive sim is an unusual genre, at times capable of really capturing the imaginations of a wide audience and drawing them into a complex world of action and consequence, of simulation within a freeform environment, and then it so often peters out. Part of that is surely to be with the games themselves and marketing, as titles seen as a new dawn for the genre like Deus Ex: Human Revolution and Dishonored are then followed by sequels that dont have the same success at the tills, but its odd how there are such distinct peaks and troughs.”
