i think that WIF have nothing to do with history, but agree with you that is fun and give players many opportunities of follow different ideas.ORIGINAL: warspite1
For me, WIF can follow history but can also provide, and indeed is more likely to provide, many different variations on a theme.
but I think WIF is the perfect mix of a broadly historical game that is fun to play and presents each player with thousands of opportunties for new/different ideas.
an example of different ideas: in my current games, Japan player Dow CW in M/J 40, a complete surprise.
an example of nothing to do with history: in my first Wif games, as German, against very experienced players, i conquer Russia, UK (after russia) losing 3 corps 6 div and same aircrats unit
