All of those killer old-school, Renaissance-style cRPGs that have arrived thanks to crowdfunding have been making their way to consoles lately. There's no question that they are far better experiences when you ditch the controller.
For a tactical RPG like Wasteland 2, the ability to roll over and click on-screen elements, or to quickly tap keyboard shortcuts, is a huge part of the game's overall feel and style. There's just something lost when playing with a controller.
Follow-up Wasteland 3 (set in the snowy post-apocalyptic Colorado landscape) will drop later this year, and if history is any indication, we can expect console versions to follow at some point. And all of those should support mouse and keyboard, especially in 2019.
There's really no excuse for them not to.
