Then, if money does not matter, buy Europe1940 2nd edition and Pacific1940 2nd edition and combine them to Global1940 2nd edition.
From the A&A games this is definitely the biggest, most complicated game with lots of (different) units.
If money is an issue, buy ‘1942, 2nd Edition’ - it covers the latest ruleset - but is a simplification of course.
No reason to buy a game as outdated as Revised (except for collecting purposes), IMHO.
@elkikko:
…
What i expext is units like mechanized, rockets, tank, super tank, helicopters,… But only if the version is the best for you
So the above mentioned Global comes close to your needs (though you won’t find all those units you mentioned).
