Why would you want this? Have you ever played a city builder on a controller? A Mouse/Keyboard is always going to be the preferred control method. Games released on the original PS One and Sega Saturn of this genre pretty much all included optional mouse support. I'm not saying a controller can't work, but it's just never as intuitive. Of course, since MS won't allow you to plug a keyboard or mouse into it's native USB ports

, there isn't really a better option for the console version. But I can't see there being a huge demand for people to play a game with worse controls on a PC personally.
1. It shouldn't matter to you why I want it.
2. If you read my posts, yes I've played many city builders on a controller.
Anyway, it's great that you prefer mouse and keyboard but I'm not asking them to remove your mouse and keyboard support, so I don't know why this matters to you at all. My point is that the work is done to add a controller UI with the console versions and I'm inquiring as to the viability of getting that code in the PC version. Some devs have the code so similar it's not an issue at all. Some are built completely differently and I understand why it doesn't happen in that case.
This is just me asking.
And for your future reference, not everybody CAN use a mouse and keyboard. There are millions of people with disabilities that cannot use a mouse and keyboard for various reasons. Me, personally, I sit at my computer all day for my job and I like to play games on the couch with a controller. Fortunately, many feel the same way, which is why controller support is so widespread these days.
Hope you have a lovely day, but honestly, this topic had nothing to do with you.
