It's odd that in history the Allies were off guard and reacting to Blitzkrieg and on an initial defensive, but from the start in this game, it's the opposite. The Allies have the choices that effect the rest of the game and the mobility advantage in most areas of the game.
In history the allies have the mobile advantage at the end/mid of 1942 in africa (russian later)
Or just thing about 1943-1945 when the US and British started to storm Europe...
history is not he best argument for a RTS
pak to t1 = us forces is even more fun
= vs soviet t1 is....
