Users attempting to play Deus Ex: The Fall, released yesterday, on a jailbroken device will be in for a bit of a shock when they attempt to fire a weapon, and nothing happens. It seems that in order to get the full experience of the game, players must be using a non-jailbroken device. Reddit user KipEnyan, posted this image of what jailbreakers playing The Fall see when they attempt to fire.
Certainly, some users jailbreak their iOS device to use pirated software, but it is not a one-to-one correlation. While this is obviously an anti-piracy measure, it is a predictably short-sighted one, and people who would actually pirate the game will find a way around it. Instead, Square Enix is punishing consumers simply for modifying their device.
There are a number of developers that actually do the work to make it difficult for people to use pirated versions of their software, and you'd think Square Enix, which can put more resources behind this problem, would be able to find a way to make it harder for pirates to crack their game. Instead, they took the unthinking, anti-consumer route, and the only people hurt by this move will be their own paying customers.
