It won't be like Rogue, because that ran on older iteration of the engine. This one will run on the same iteration as Unity, hopefully with less shit performance.

Also, Rogue got downgraded a bit - draw distance and level of detail connected with it was reduced compared to AC4, which is also why it ran so well on good rigs.
