In an interview with PCGamesN, Creative Assembly brand manager Rob Bartholomew said after the team logged in to Steam to mess around with the default controls of the Steam Controller, they determined they could come up with a controller configuration for the game “within half an hour, certainly within an hour.”
Bartholomew said the default controller setting essentially uses the right trackpad to move the mouse and the left trackpad to move the camera in the games Battle and Campaign modes, with the triggers doing “left and right output.”
And instead of allowing the default controller be applied to Total War: Rome 2, just like it would with any other new games without developer customized control settings, Creative Assembly felt good about creating and distributing its own controller configuration for the game.
“The whole team felt pretty good about that being the control mechanism, and then we could just release that online and guys can share that or customize or add to it or just scrap the whole thing and design their own control config for the controller,” Bartholomew said.
Bartholomew did say the development team would make “some concessions” in terms of the games user interface, but that the Steam Controller has the attributes of a mouse and keyboard “at least 99 percent of the time."
