Basically this. We never stay on topic for very long before we start talking about everything else, usually not even related to the topic. We are pretty lax on this stuff. Never fear. This is quite normal.
Don't worry, I'm also used to this elsewhere, I usually just say that.
Is this the part where we happy dance?
Oh, and Mario RPG actually had star collecting too, with the fifth star being a blue star just like Thousand-Year door. The chapter in both also involved pirates and ghosts.
Remember, Mario also appear in Bowser as a memory in the brain in BIS. He was one half of the boss fight and he even used his classic moves. ^_^
Even as Bowser's being the final boss, i think a Master Crown styled final boss would have been better, think about it the sticker crowns kind of drove Bowser and his minions insane, so it would have been cool if, as a result of Bowser's evil heart, that the last sticker crown turned evil and then proceeded to turn Bowser into a Magolor soul-like form.
