While talking to various people over the last couple of weeks it looks like there is a lot of support for the concept of giant smashy robots/beasts beating the tar out of each other, rather than seeing increasing amounts of infantry getting in the way of said smashing!
In essence these games are based solely on the rule below (p92 of the Prime rulebook):
Each player is allowed only a single warcaster. Besides its one warcaster, each army can include only warjacks; units and solos have no place in Mangled Metal.
Would anyone care to give it a go?
