How to make TL11-12 challenging?

jeudi 30 avril 2015

So I plan on GMing again and I'm thinking of planning to explore at a very high ultratech level campaign, but with all the gizmos and such, it seem almost every solution can be sloved unless the opponents is also TL11-12.

Also examples of fiction that set in TL11-12.

I plan on divergent of TL7+4-7+5 of "spiritpunk", where spiritual engery was an answer to the environment problems caused by TL7.
