I hope we can. I love this game. It's my favourite Wii U game so far. It's brilliant genuine platforming fun, almost on par with the Galaxy series. Reviewers said it was short and easy. Haven't beat it yet, but it's not the longest game I think. However it's pretty challenging later on, so I doubt these folks played past world 8. It contains some of the most frustrating Mario moments to me, and I'm not even at the final level yet. The Mario Kart level in world 3 was brilliant, as are the levels in which you have to use the gamepad.
Did anyone else also really enjoy looking for 8-bit Luigis? I think they're pretty awesome easter eggs, it was amazing seeing him for the first few times.
