This game is not exactly like any Harvest Moon game really, in terms of how the game feels I would say it's closest to BtN if you had to compare. And FoMT and MFoMT are based on BtN I believe. But yeah I really loved all of the festivals.
The dancing, the ocarina playing, the fireworks, the hot air balloon, the swimming, the egg hunt. It was all really fun to me.
Then the music was nice, I liked the graphics a lot, the more isometric view was nice to me, and you could change views if you really wanted too in some places.
