Xbox 360 controller for me, but I'll have to get something else come next year. What are some good options?
It's still a controller, but the PC drivers for the XBOXONE controller should arrive "in 2014" according to MicroSoft. So anyone having an XboxOne (anyone, anyone, Bueller, Bueller...) has another option to add to the pile. How it maps I don't know, but would guess the buttons will poll identically to their 360 counterparts.
Not owning either console or their controllers I have no idea what advantages they would have over each other.
Personally, and driven by desk real estate, I'll be with old-schools keys and mouse, if necessary I'll use a controller. To get an X52 or similar will involve buying a new desk, which necessitates a new study, which needs a new house. That would make this the most expensive game ever by quite some margin.
