The game is really great, it has good combat, and it can be very addictive, like a lot of RPGs.
I recommend a physical copy to aquire the music CD/guide that come with the game. I didn't honestly find the music that memorable, but whatever. . .~
Trust me, you're going to want the guide at time though, as the quests don't fully explain what you need to do, and at times you may find yourself getting stuck on random new things that you wouldn't expect you would have to do (like accepting quests or speaking with certain people).
My first recommendation if you get the game: TALK TO EVERYONE; EVERYONE~!
