Ubisoft has no fewer than three different Assassin's Creed games in development, reports Kotaku, quote Ubisoft CEO Yves Guillemot saying it is their goal to continue to make the assassination series "appealing and fresh" in spite of the apparent overkill. Here's a bit where he uses the words innovation and formula in the same breath: "Really, what we see is that we can have the capacity to regularly come with innovation," Guillemot told Kotaku's Stephen Totilo. "That is, for me, the formula: if you can really change the game on a regular basis and bring in innovation your fans want a product very regularly. Our job is to make sure the teams have enough power, enough energy and enough time to take the necessary steps to create a high quality game."
