6. Loco Roco 2
Forget about me explaining what the hell this games about, I'll just say the gameplay is phenomenal as it is inventive, the art direction is rad, and the soundtrack is sooooo annoying that not even batman's iron will could save him from going batshit (horrible pun) insane!!!
But like every other game I adore, sales were... pft. Let us speak of them no more! Because not even playing the bright and fun Locoroco 2 could cheer me up
