Is this the first Xenoblade? If yes... then the answer is yes. I havent seen a single person who hasnt loved it. It delivers something that open worlds failed to do in the past: a really good story and characters.
I would point the only weak point as beeing the combat getting repetitive after a hundread hours, but everything in the game feel rewarding. Its definitly very enjoyable. Go for it.
I want to make an adendum to the above posters statement. Yes, there are some kill X quests, but these usually take you to areas that you havent explored yet and the discovery of those areas also unlocks further rewards. It didnt feel boring for me, but i can understand how it can. Since i was discovering a new portion of the map, it was never a problem for me.
