Why FF XIII sucks, in perspective:
- Linear as hell. Seriously, no exploration at all. Even FF XII could at least give us that.
- Make it or break it battle system. You will either love or hate the battle system, and it takes more than a few hours before the game has finally told you everything you need to know, and you have the proper party, to be able to use said battle system.
- The character development is flat, unappealing, and probably some of the worst since early FF's that couldn't provide much character development.
- There aren't really shops or towns. There are just kind of save points with everything. If you don't like towns, I guess it can be a plus.
LBP2 provides more, enhanced LBP fun. From what I gather, it is kind of like a super enhanced LBP1. If you played and liked LBP1, you will more than likely enjoy LBP2. It all depends on how interested you are in the PSN content though.
In all honesty, I would probably pick up something outside of those two games.
