online; I’ve only played Mario Kart 8 DX online and it’s been consistenyl the most fun I’ve ever had since Left 4 Dead 2. The big advantage is that there is no online voice caht, so no little pricks calling you a “fuckin faggot” every thirty seconds - though I am assuming that is what online gaming is still like.
The gameplay online is as solid as I need it to be tbh. everyone is a million time better than I am I I only manage just to keep my score above 1000 (you start at 1000 and it drops if you do shit on MK8DX).
the controllers are amazing. my wife and I play MK8DX most nights, and our longest marathon last five hours and neither her nor I got sore hand from holding the controllers in the sideways config. as a portable the thing’s most comfortable than my DS I played hundreds of hours on, and the pack-in controller housing thing is pretty comfortable too.
I don’t have a pro controller, so I can’t say, but I have no need for one.
