klonoa and shantae both peaked with one really solid game, that being said, those games are good and you should play them
door to phantomile and pirates curse. In my opinion, the rest of shantae is bad while the rest of klonoa is just mediocre.

as for the phantasy reverie package, its a port of the shitty wii version. while the cutscenes are "passable", it doesnt hold a candle to the original's charm.
I recommend emulating DTP. namco doesnt give two shits about klonoa anymore so I dont feel bad for telling you to pirate or emulate. klonoa isnt making a comeback.
