this was a casual playthrough I did in one go a little over 3 years ago, pretty sure I pulled a muscle while doing this haha. Tons of time to save since I took many breaks to catch my breath. Done on legit hardware, US Disc on US Wii, using the Active Life gamepad + webcam recording me using the gamepad + wiimote & nunchuck (for pausing and menuing). Selected the newly created file at 4:23 in the video, final input before credits roll at 5:05:15 in the video. Sub 4 is definitely possible, sub 3 hours might be difficult to pull off, but it's probably doable.
