I really like how Yuffie plays. She's fast, fun, and makes use of abilities that are distinct from the others(the only thing annoying about her is the lack of a skill to rack up stagger, at least from the weapons that I used.)

I even had fun with the RTS minigame, and it was cool how parallel it ran to give us new perspective on the main plot. However, the villains and indulgent Nomura designs full of Nomura-isms that are pretty cringe and have no overall impact on the plot. Yeah, it's the Halo Reach effect except like every other square enix trio of characters, you don't get to know anybody well enough to have their character arcs actually land. I do however like what the ending ending does a bit for Yuffie's character, someone who was very devoid of development before.

The Shinra experiment stuff is also way too convoluted, even by FF7 standards. You just can't think about it, then you can have a lot of fun with this short DLC.
