Yeah I think calling XIII-2's OST lazy is a bit much. It's okay though but I still prefer XIII's. (I haven't heard all the music yet so it might change!)
Anyway some mid-game impressions (11 hours in):
- The camera is wonky for some reason, when it focuses on the NPC and when it zooms into particular areas. XIII's camera was totally fine for me though.
- I'm glad you can talk and interact to specific NPCs. Adding to that all them have voices too. My only problem is that they seem kind of... Off I guess. Like they'd walk into walls. I chuckled when they started jumping from wide ledges.
- Episode 4's first location looks great
... Kinda like FFXIII Sanctum but better.
- I liked Noel, Serah, and probably Mog's characterization. They're not loathe-worthy nor are they over-the-top annoying. I prefer their characterizations than XIII's.
- The story doesn't seem so bad... Nor convoluted to me for now.
I'm finding the game a lot fun to be honest.
