"Don't be a retard"
But there's a billon
I think these questions really test your memory of the games. Personally I only knew about TTYD and Super Paper Mario so the hardest part for me was the first game.
Also, for the question in The Paper Mario section about what can get you x amount of star pieces, the bottom left answer doesn't do anything. It was incorrect, but it didn't do anything when I clicked it. That is all.
what are the answers?
Ummmm... The order of the games is Paper Mario, Paper Mario Thousand Year Door, Super Paper Mario, Paper MArio Sticker Star. Thousand Year Door has the Pit Of 100 Trials. thats my correction on this.
