Well, on Europe page 31, it says to follow the rules and setup information found in both Europe and Pacific unless otherwise indicated in this rules set.
Oh, I see what you’re talking about. Well that sentence says to consult the Pacific 1940 rulebook for Kamikaze attacks, China rules, and so on
“And so on” must include island complex rules. I don’t remember anything in the Europe rulebook that would alter the no island complex rule, and I’m sure there’s not anything or someone would have brought it up in the past year on this thread.
