IM GOING TO ORGANIZE THESE BY GAME HANG ON

katamari damacy - make a star 4, make a star 8, make the moon
we love katamari - bird stage/as large as possible 5, the ending stage, all stages really,
m+mk - camel stage, gorilla stage
beautiful katamari - neptune stage, vega stage (dlc), chateau notre desir stage (dlc)
katamari forever - scorpius, cetus, sprinkler, wake up the king, farewell
tmk - the old man stage, the great journey stage (dlc)

Thats all the main games i think but ive never met a stage i didnt like and if i did i would have a very good reason to because i love this series
