Paper Mario Sticker Star.

I purchased my 3DS
FOR.
THIS.
GAME.

I thought it was going to play like the first two games and pre-release shots showed a chainchomp partner, so I was super hyped for the game. Then I bought it, annnnd . . . wow. I was bored the whole way through, normal encounters were actively detrimental, and everything was tedious; it was a miserable slog through the game.

Oh, and I never got my chain chomp. Q_Q
