I just consider them farming simulators with a really cute aesthetic, not really open world, but you can do basically whatever you want. I didn't really like the one on wii. of the newer ones I'd recommend Wonderful life, Magical Melody and another wonderful life, basically the gamecube ones. The N64 and SNES versions are awesome too, not as complex, but still really fun but pricey as well and back to Nature is fun too
