Koops, King of Cowards.
I don't necessarily think they have to go back to the old formula to be good tho. I mean, as attested by even the sales of the last two games the series is still doing great for people outside of the vocal minority that values story. I would say myself included but I sadly haven't played either of the two but all I really want is a game that's fun and enjoyable. Preferably with unique character designs to please everyone else I guess (although the characters really need, well... character, most importantly)? The ideal scenario is that this game brings the best of both worlds, so that way everyone's happy. Heck this game looks to have the same basic qualities as Paper Mario 64 (level design that rewards exploration) and a fun battle system. As long as I have these two elements I'll be happy. And good writing already looks present.
