Quoted from slochar:No reason to hesitate the building will still work. Is there something in the prototype gameplay that got axed in the later production?
The lamp shows are different for sure but iirc the proto lamp show was pretty rudimentary.
Honestly not sure. I had only briefly played an ES once before at a show and it was before I understood rules and stuff. Also the one I played was in rough shape and I couldn’t hear it. This lead to a less than stellar experience.
