An Xbox One version of Assassin's Creed: Rogue isn't entirely out of the question, if comments from Ubisoft Sofia producer Ivan Balabanov are anything to go by. Assassin's Creed: Unity is very much Ubisoft's focus for new generation hardware at the time of writing, however.
Speaking to OXM at Gamescom today, Balabanov described some of the optimisations the developer has made to systems from Assassin's Creed 4: Black Flag and Assassin's Creed 3. The new game's River Valley region apparently represents almost as much landmass as Assassin's Creed 4's Caribbean.
The latter's sailing and the third game's wilderness areas required the "full capacity" of the platform at the time of release, but Ubisoft Sofia has managed to "squeeze out more memory" by rewriting code to be more efficient, allowing the two systems to coexist - and with optimisations to the frame rate to boot.
Wouldn't it have been easier just to run the game on Xbox One, I asked Balabanov? Ah, but that would be treading on Unity's toes. "The [Unity] technology's built from the ground up with a lot of reinventions of the systems behind it - essentially it's a game that takes full advantage of the hardware, and what we wanted to do in our case is make a game for players who still haven't made the transition."
Still, is a port possible at some point after release, once the buzz over Unity has died down? "It's too early to discuss this subject. Right now Unity is our game for new generation consoles."
I played Rogue for the first time following our conversation. Highlight: demolishing an iceberg to create a tidal wave that smashes an enemy vessel against the coast. Look out for a full report later on.
