I want to play it with a controller because you have to admit it drives a lot better.
Yes, either with a cable or with an adapter for 20 euro that also works wirelessly. But if you play with cable there are no costs
Can you also play wirelessly for free?
Yes, connect your controller to your mobile phone via Bluetooth
Only if you have a special controller, which in that case is no longer free if you don't happen to have it.
There's no SPECIAL controller
