RTS- Revised Transition Syndrome is where you look at the revised map and keep moving things around on it like it is the Classic map.
When we first started Revised my many many games of Classic opponent had to be constantly told, “can’t move that there.” Three times on his first US move he tried to put his SZ10 transports in SZ2, “that is where I always move them.” There are a few other things like the inside/outside seazones around Japan. He kept trying to move TRNs from the outside zone to Wake or the Philipines and landing in Manchuria his first game as Axis.
Does that make any sense?
