Sure dude, you know the game where you blink and turn your back on the monster, and it comes closer. That would be a hilarious game mode. What system do you guys use to make Pokemon 3D? (or maybe a link to it because I am sure this is a very well asked question?)
The engine is written from scratch by nilllzz.
we dont use anything like unity or something if that is what you wanted to know
but we made this system in hopes that people would take the opportunity to create their own story lines or recreate a story line they found elsewhere(not the main games) like a rom-hack or something.
All of the maps and scripts are 100% change-able and are all text files that can be opened in notepad or something similar.
