Just about every game from Platinum games are interesting but so far I have only played Bayonetta, and not for that long. The over the top action was to much for my small brain to handle. Watched a few of the games being played and Nier Automata is such a cool experience even for the onlookers, that got my vote.
But Madworld is just so unique in a stupid way. Need to play that thing. Childish game with extreme violence in a stylistic setting - not something one gets to play that often. If it ever gets a re release of some sort I have to pick it up.
