I actually imported Battride War II...CDJapan had the Sound Edition for 102$, which was pretty good...
But I ended up canceling it. Unfortunately from what I've been reading, it's barely an improvement over the original (which I had a lot of fun with), and not worth it unless you missed out on the first one.
Besides the obvious lack of new characters, apparently the mission structure hasn't been improved whatsoever, and in-fact I hear the missions are even more repetitive than in the original. They also skimped out on dialogue this time around, apparently everything's basically just recycled from the first and lifted from the movies. Even the "Kamen Rider Movie!" theme is lacking, with no Orga for Faiz for instance, or a fight with that giant Orphenoch which would've been amazing.
I've read there are apparently six slots for possible DLC or something in addition to the two for Kiwami/Zangetsu, so if the price drops and some cool DLC characters come out, I might reconsider. I wonder if they'll continue the Movie Theme and add in Kamuro/Mars once the Gaim Summer Movie comes out, I imagine the rest of the DLC would be Gaim Riders since they're easy to get the VA to come back, so maybe Malika and Duke. Don't know if they'd release Micchy DLC since he's already an assist.
Still can't believe they missed the obvious playable secondaries. If they would've done that, I would've bought this game without hesitation.
