It'd have to be Final Fantas 13-2, I've played most of the FF games but none of them seem as good as 13-2. Well why it's my favorite?
1: Characters- easy to relate with, even the villian has his issues I can relate with the villian as well.
2: The graphics- Graphics aren't everything...but damn these vibrant enviroments are the shit O w O
3: Moogle- Whut?
4: LVL system- Best one I've seen so far, don't gotta grind so much like in most FF games.
5: Music- Best soundtrack I've heard for FF, 10 and 7 have good soundtracks as well...but I've never liked so many songs in one game such as this.
and finally
6: Story- A story about time travel, only played one game having to do with Time travel and that was Shadow of destiny...Final fantasy has done a good job making a meaningful story about time travel At first I was skeptical but I enjoyed it.
