Looks like the PS4 vs Xbox One battle is turning one-sided as far as sales victories are concerned....
Assassins Creed: Utopia – A City Builder Simulator For Mobile Devices
Set just before Assassins Creed 3, In Utopia, the player is a pioneer building an entire community over the course of 150 years during the early colonial period of American history. You’ll be making decisions regarding how the town grows and thrives until the outbreak of war that signals the American Revolution.
Your settlement will also house the New World’s first and finest band of Assassins. You’ll be able to pit their strength against your friends in asychronous 3D brawls, or enlist their help to defeat foes in “limited time epic battles”.
Ubisoft has explicitly stated that “There are no links between the games, but the narrative will lead into the AC3 narrative, since it’s a kind of pre-era to the Assassin’s Creed 3 era”. Also there are no other incentives to play Utopia besides wanting to play Utopia. The publisher has also affirmed that purchasing or playing the mobile game will not unlock content for AC3.
Utopia currently has a vague “winter” release date. Presumably Ubisoft will want it to accompany Assassin’s Creed 3, which launches for PlayStation 3 and Xbox 360 on 31st October.
