Isn't Poland part of the Second Wold? Seeing as it was part of the Soviet Union's domain back when the phrases were coined. First world is the west, second world Russia and their iron curtain etc, and third world countries that weren't (directly) involved.
Anyway, back on topic, I'm glad to see some movement with this issue. I wonder if some people could see it better if say every game that have had a version of the FG42 were compared side to side. This would make the copying clear and similarity separate.
