I would not be G40 boxed set for a new rulebook or even for new French unit sculpts. However, I would buy a G40 boxed set for some combination of two or more of these changes:
1. Long standing balance issues were resolved officially instead of with the house rule hodgepodge we use now.
2. Historical inaccurances (Scapa Flow, Iceland, Sierra Leone, etc) were corrected on the map/setup (for instance, Iceland was occupied by the US on July 7th 1941, but the map shows it as a UK territory from the start).
3. There were cool new sculpts for multiple powers, and cleaned up sculpts for units that look too similar (ANZAC cruiser vs destroyer for instance, or corrected the 9 ft tall ANZAC infantry unit).
4. New map! For instance, eastern Russia is vast and would have been a Japanese sinkhole that brought no benefit, but in the G40 map those territories all actually produce income. The Global War map is a much better representation – combined German/Japan strategies that work on the current map would not work on Global War map.
5. Map supports faster setup – MICs and setup bases pre-printed, for instance.
6. Rule changes that allow the US to build bases on other Allies territories.
7. Rule changes to fix unit issues (cruisers!)
8. Separate control markers for UK Pacific vs UK Atlantic
Basically, a couple of big changes or a bunch of small changes make the investment worthwhile IMO.
Fixing NOs could be part of #1 – giving the UK an additional NO of no German navy in the Atlantic other than sea zone 112 would probably help the balance issue. Also, giving Japan an NO that costs it money if it DOESN’T control those islands once at war with the US might help the balance issue.
