The expansion pack is called the Shivering Isles.
Back to the original topic, I enjoyed Enchanted Arms when I bought it on the 360, as I am a big Final Fantasy fan, and I quite enjoyed it. However the game does feel a bit short compared to the FF series, and in this case I'm going to have to recommend that you get Oblivion.
It is a game that you must experience, and it will last you for quite a long time, because there are so many things to do, many side quests to complete, many characters to interact with, so many different ways to play, and some of the most gorgeous looking graphics you'll see in a game, especially on the PS3.
