I found it way too easy to be any fun myself. When I had FSA, I and my brother beat it maybe two days max... So, maybe a party game if you have a lot of people, but I didn't even find it all that fun...*shrug*
Well, it does have some important story stuff, like the Four Sword for example. But I do find it slightly easy. Not to say it should not be taken seriously, since I do consider it a part of the main series, but it is quite easy, and I do not blame you if you choose not to play it.
