I can't help but wonder who the target audience is for ports like this and Resident Evil. When Nintendo are obviously kid-friendly, it makes little sense to put these sorts of games on there. It's amazing what they've done with Witcher but again, why would I want to play it on a handheld with reduced graphics, when I can play it on a massive TV.
I don't have a Switch, so...what's "HD rumble"?
Nothing really. The joy cons have more refined rumble vibrations than you would find in a normal controller. I don't think the rumble is anywhere near as strong as a Dualshock 4.
