Made a few over some time ago for a project I'm currently working on...
one of the starting areas of the project:
an attempt at a special battle... it supposedly merged frontview, with a parallel event-based sideview battle
It got better over time...
even MUCH better when I added the right adds to the fight, (and the heavy machine gun sfx syncs perfectly to the animation so I kinda came here)
so yeah, guys deal with agents on frontview, you can spend Sesi's turn to pilot the robot on sideview vs another robot. all purely done with events

These kinds of battles needed some kind of setting... so I started to map out a decent city-place, these were the runner up tileset comparisons:
Eventually I completed the city... gotta say, I can easily get 2-3 hours of solid gameplay out of it, should I properly start to map the interiors XD
