[quote name='Excast']Both have great stories.
I like that they are not set in the typical fantasy setting. There is an aspect to them in which the game is half making the day to day choices that shape the character's life and how you deal with others...while the other half is the dungeon crawling. While said dungeon crawling can get repetitive, the battles are very fun and fast paced.[/QUOTE]
I'm still working on finishing 3 and while it is a time sink (100+ hours on the game) the characters and the storyline have kept it fresh for me. As others have said, it isn't your typical JRPG.
While I'd like to own 4, I also have a huge backlog of games, so I'll pass this time.
