I realize that economical issues and lack of time might make it impossible...just want to know what people thinks about it
I think 2 Cantrs would be good for interesting new people to the game(s).
A lot of people would like a purely medieval game, and many want to play a modern game. Even more would like both
When the mysterious Cantr 2.0 will come I think it will be perfect for launching the other Cantr and keeping that to merely medieval inventions.
