I must be on a roll this weekend! Once Gloomtail was out of the way, I did wonder if Paper Mario 2 was going to suffer from The SuckySuck(TM) bit that many games do; namely, recycle all of the bosses one after another before the end boss (see Feel the Magic, Viewtiful Joe, etc.). Luckily, it didn’t.
Between Gloomtail and the end, there was a fairly long puzzley bit, and then it was muliple-boss time. Grodus, Bowser, Kammi, and then [spoiler]. And then the longest end of game sequence EVAAR. But it was best, and so am I. Obviously.
