The more I watched, the more convinced I became that this was half-informative and half-satirical. Especially this gem:
Love it. It's glorious. It's full of charm and I chuckled the way through it. They need to do more of this. I know they've used some All The Bravest sprites, and they've made new FFXIII-2 ones as well (Mog looking like he/she's the FFVI Mog though), which is more than enough to say that when it comes to pixel art and design, they still have it in them.
It just makes me wonder why the FFV and FFVI mobile ports have to feature those kind of plasticine, charmless sprites. And why Square isn't putting these sprite skills to good work on a good, original, smaller-scale spinoff FF game for handhelds and mobiles. If they ever choose to "demake" the Lightning trilogy like this, I'll buy it in a heartbeat. At the very least I want more of these cute video demakes. Someone should follow up with a FFX and X-2 retrospective demake video when the remaster is about to come out!
