Punished_Snake: But on solo is this similar to Minish cap (when you have the full powered minish sword), gameplay side?
No, not really. Minish Cap is way better than Four Swords Adventures, gameplay-wise. FSA is at its best when you play with friends, controlling four Links at once can get a bit cumbersome at times. Still, what AnimalMother said is correct, while playing with other people is loads of fun, it gets a bit hectic, and if you care for story progression, then you're better off playing on your own.
It's not as good as the "regular" Zeldas, but it's a great game, nonetheless. The mechanics in Minish Cap work better because it was developed as a single-player game, so it is more polish in that regard. The gameplay in Four Swords Adventures works well enough for what it is, and some puzzles are really clever in the way they use the four player mechanic, but it's a bit cumbersome when you're playing alone and have to cycle through individual Links in order to solve some of the puzzles.
