Final Fantasy Tactics director Yasumi Matsuno shares early development sample images of FFT when it was planned to be an Ogre Battle style "RTS" (auto-battler?)
I really wish we had more Ogre Battle style games. Ogre Battle 64 was good shit but it suffered from balance issues and some incredibly opaque mechanics.
Vagrant Story and it's non-linear dungeons and deep weapon crafting system walled me as a kid. I wasn't able to beat it until I was an adult and had the internet and a guide.
