This is not a joke! Microsoft just announced that Cities: Skylines will be coming to Xbox One console at some point next year. We already got our first hint of CSL on gaming controllers with the Steam Controller advertisement.
We don’t know yet if it’s coming also to PlayStation 4. Microsoft didn’t point out that it’s a Xbox One exclucive, so there is a chance.
Mouse and Keyboard support for Xbox One was announced a few weeks ago, so the controls might be done with them.
Mod support and possible fps issues are still mysteries.
