So, just to know, are there more people here that are going to make a physical game?
Sorry, I didn't understand the question. I am making a little ttrpg myself. I used to play Battletech back in the day and I always found the mecha genre flawed by really complicated rules. I want to do a minimalistic ruleset in 3-4 pages (it helps as well for people reading it easier than a 150 pages one XD).
When it comes to art, I usually draw some doodles myself or use stock art. This one here is a lot of images for free. Or here.
I am going to do a little PbtA game where the characters are the cadets in a mecha pilot academy first with all the teen drama and, once graduated, they ride mechas and fight the enemy. I am quite sure that, as a concept, that has been done in some anime but right now, I have no idea which one and could use some documentation XDD
