I do think about this game a lot, as it was probably one of the most intense gaming experiences of my existence.
The game was so convoluted and so unpredictable that I still remember it as a lucid dream.
The music, the revolutianary play style that has you switching from 2D to 3D, the puzzles and the backtrack...
The story was PACKED of amazing moments, and the amount of content that was in the aftergame was insane. I still legitimately have nightmares about the 100 floors maze that came after the game.

Bautiful experience, only downside to this game is the fact that every Paper Mario that came afterwards sucked big time
