or, How I Learned to Stop Worrying and Realize This Assgrab is Delicious
I took DLC stuff to be a new normal for FF.XIII-2 seemed very intent on tapping into the western RPG playerbase, or at the least learning what makes them WRPGs tick. I think it was as much a learning/experimental experience for Square that they were willing to take considering it was fundamentally not a mainline game, and with Tri-Ace developing a lot of it. Many of its subsystems are literally staples of WRPG.
Non-linear story progression, check
Dialogue options, check (lol)
QTE, check (god damnit)
Vast array of recruitable party members, check, sorta (this was done in previous FF games though)
Multiple endings, check
Interactive/dynamic music, check
Lots and lots of DLC strung out on a pseudo-fixed schedule, check
Story DLC (lol), check
LR had costumes you could buy, and if it were a larger release, I wouldn't have been surprised if it had story DLC too.
I wouldn't be surprised at all to see extensive DLC when XV finally releases.
