only did the main story this time around but still a really excellent follow up to pikmin 1. i know a lot of people don't like the de-emphasized time limit or the dungeons but both of those are huge pluses to me, the only real issue is that combat is pretty imbalanced and kinda jank. random generation in dungeons isn't 100% great either, leads to them being kinda basic monster fight stuff or relying really heavily on troll design (which i like, but there could be more interesting stuff too). the interplay between the two sides of the game is pretty fun, but i think there could still be more done. maybe having separate squads on overworld and caves to up the multitasking, or just having more puzzle solving beyond what pikmin are best against what enemies
treasures are really excellent, easily my fav collectable in any of these games. pikmin 2 is very surprisingly anti-capitalist for a mid-2000s nintendo game, it's super charming.
