Finally had the time to sit down and inspect the new trailer and gameplay footage.
We can see how the two additional materia slots are added to the UI after Zack is promoted to 1st Class. If I had to guess, I'd say these will be mapped to R1 and R2 (while holding L1).
Oddly, switching targets is done by holding L1 (which is already used to open the materia menu) and flicking the right stick. In Remake, only the right stick is used to switch targets. I found this discrepancy odd at first, but then I began to consider the "soft lock-on" that Crisis Core utilizes.
In the original, there was no lock-on button nor a way to adjust the camera yourself in battle. Instead, Zack automatically locked on to whatever target he was facing. With Reunion, both a lock-on button and camera control were added, but the game still uses a "soft lock-on" system like the original. If I had to guess, I'd say L1 + RS are used to adjust the soft lock-on when casting magic. When locked on with R3, then perhaps target selection will function like Remake. Hopefully it feels good in motion.
Just gotta say that the Ability Power gauge is going to make Hard mode significantly easier, which is a good thing. The unblockable attacks in the original forced you to create materia with a high HP% boost, as well as have barrier/mbarrier active at all times, which got stale.
The DMW photo remembrances appear right over the reels now. Love it. Just to clarify, the video remembrances are still full screen.
Anyone have an idea what those little blue numbers under the materia icon mean? They weren't in the original, and they don't represent the casting cost, level, or stat boost. Perhaps it's how much SP they're worth with the SP Convert feature?
