Dark Souls II lives up to the series' reputation for being unrelentingly difficult- but it's worth digging in your heels and spending a lot of time with it. The PC port is just as good, if not better than it's console counterpart, but you're going to want to use a gamepad. Using a keyboard is possible, and there's even a few mods out there to make it more functional and ergonomic, but it's still clunky and unintuitive compared to using a controller.
