The last three games – D-Day, Battle of the Bulge and Guadalcanal are a bit of apples to oranges to compare them to Revised, Europe and Pacific.
The first thing is do you need more than two players? DD, BOTB, GCNL are best as two player games.
D-Day is IMO the weakest version. It is good for teaching those completely unfamiliar with wargames or when the game is secondary to just being social.
Battle of the Bulge is the best example of a classic wargame (trying to put you in the spot of the commanders.) It has a radically different combat system and a hexagonal map board. It is the least like Revised of the two player games. It has a supply aspect that tests not only your tactics but logistics. (This is my favorite so far.)
All for now. But I’ll be back a bit later tonight.
Mods– this should probably move to ‘Player Help.’ (Thanks Fish!!!) 8-)
