Paper Mario? Was the sh**. Only 2 complaints I had about it were that:
1. You cannot keep playing after the ending. After you beat Bowser and go through the credits and what not, when you try to play again you start off at the last Save Block you hit (which is usually the one next to the spiral staircase that leads to Bowser and Peach, wayyyyyyyy in the castle lol). They fixed this in the next Paper Marios, but I always wondered how amazing the first would have been with that changed.
2. I wish they had it where when you traded Star Pieces for Badges with Merlon's Son or Grandson, that in the event you didn't have enough star pieces that you could buy them with coins (even for an absurd amount like 600+ or 999.) I understand they wanted people to collect all the star pieces, and every run of the game unless I felt like doing otherwise I collected them all, but it would be nice for people who didn't want to have to run around EVERYWHERE flipping over Panels in the ground to get every single piece.
3rd minor: Out of 80ish badges I think, a TON of those are simply duplicate badges that you stack (HP plus, FP Plus, Shrink Stomp, Dizzy Stomp, Focus, Multibounce, etc). Like I can understand having a few of them stack up like the HP and FP plus, and maybe even Focus since that dealt with your Star Spirit Meter, but like there was no need for 2-3 attacking badges stacked on each other for like 7-10 badges lol.
