I have a few ideas but ideally I would like someone else to take the reigns of GM if they were interested.

-Maybe a dark dystopian setting after the world being ravaged by war, Mecha battles mainly for fighting over resources and survival.

-Players put in a rag-tag group of survivors from various backgrounds to survive/fight the good fight

-Detailed Mecha descriptions and competitive battles with other players and NPCs

Open to any other ideas or someone taking charge.
