I think the major misstep of Odyssey was not really signalling that many of the games best moments come post-credits. Sure, some of the tasks get repetitive and searching out tiny glowing specks to ground pound isn’t amazing, but I’d certainly revisit each world a few times. I’m still finding whole, inventive 2D sections and sub-worlds 8 months later. Genuinely found my favourite new level in the game at the weekend, and I’m 793 moons in.
And also, yes. In terms of using the new platforming abilities, the post game seriously makes demands of you and your move set. You’ll regularly see moons and pipes that initially seem impossible to get to. The Koopa races also transform.
Basically, up to the credits, a fun, fairly easy retro look back on Mario aimed at casual players and kids. Post credits, an open world feast of ideas and some serious platforming demands, alongside a handful of tedious pixel hunts.
