To be honest, when I saw the footage of the game I already knew the scenario is going to be when I saw Bowser forcing the princess to marry him
*cough*Super Paper Mario*cough*:
"Mario saving the princess from the terrible Bowser", it's pretty much savvy considering Super Mario is Nintendo's cashcow on each new gaming device.
About Mario's Cap, it showed little info but like ShyGuyXXL said, it could lead into a Navy/Fi like character without shutting off about helping the gamer or "do this, do that..." scenario.
And dear lord,
the humans npc (so is the environment around him, they're enormous) in this games compared with mario characters was kinda like a huge shock to me, Nintendo always did
characters with cuter/cartoony looks on previous games, now they went full LA Noir/GTA-like NPC characters. Considering it's based on NYC with Donkey Kong references.
But the locations were beautiful, especially the forest one who owned my heart! <3
Other than that, I can't wait for more details for this game!
