@taamvan:
The theatre games (dday, Guadalcanal, bob) are cool looking and felt fresh, though they are out of print.  Unf, the attempts to make them very different from the “mainline” games also means that they are sort of unfamiliar in their execution to most people used to the bigger scale games.
Yes, they messed up on the tactical games, inventing new battle mechanics that nobody understand, and D day was even scripted, you had to land on the designated spots, and the dice decided how many units you could mobilize each turn. Not good.
What they should do if they release a new D day or battle of Normandy game, is to keep the classic A&A system. Each player collect an IPC income every turn and spend it on any kind of units at his own decision. And the units keep the classic cost, like infantry cost 3 IPC, artillery cost 4, tanks cost 6, fighters cost 10 etc. And keep the A&A combat values too, inf attack at 1 and defend at 2, tanks attack at 3 and defend at 3 or less, just like we are used to. Infantry move 1, tanks move 2 etc. Dont fix rules that are not broken. BotB really suuked.
I figure Germany goes first, as always. They purchase new units, and place them. Blockhouse is the obvious new unit, defend on 3 or less, and roll preemptive against the invaders, in the same way AA guns roll preemptive against aircrafts. Basic system. Then US goes, and on this new map there are no printed landing zones. The US player have to figure out where he wants to make his amphibious assault, and where to drop his paratroopers. If US drops his paratroops in the city of Paris, remember this game is supposed to have a larger map, then the paratroopers die, like they would in the real war, but that is the players choice, not because of scripted rules.
I figure this new D day game should have a SBR phase before general combat, just like in Global 40, where Stratecical Bombers can bomb facilities, like airfields, ports, the factories where new units are mobilized, and maybe even carpet bomb stacks of land units too, even if that would be something new. Fighters and Tacs should work the same ways as in Global 40, the way we are used to, and not in a strange strafing way with its own sequence that nobody really understand and only rarely happened during the real war.
So, what I say is, make a D day game and use the OOB Rulebook from Global 40. All A&A games should be streamlined.
