Played on release -- this game had a lot of potential, and just ended up being a pretty painfully generic Mario & Luigi game. It certainly does what it needs to gameplay-wise to be fun, but the lack of any interesting characters, enemies, or areas really hurts the game a lot. The crossover with the Paper Mario series just feels kind of meaningless, and the game gets bogged down by it's side content a little bit. Bit of a disappointment after Mario & Luigi Dream Team IMO.
