Of course I can't see any reason to actually pre-order, there are no price breaks or extra trinkets included, but if you absolutely must get this purchase out of the way, you can do so now
CMRT is my second favorite CMx2 title, after Normandy. I've had hundreds of hours of good gameplay with it.
Battlefront can go in whichever direction they darn well please. However, I am uninspired by the late-war focus.
If they had instead returned to 1941, I'd be all over it.
And that name. Of course this wasn't the original title, whatever it was was a copyright infringement, so they had to change it. I took the opportunity to suggest a few names. These are what I put forward
Across the Oder
Final Assault
Red Vengeance (maybe too much in that?)
Reckoning
For me the combat loses some of its appeal as the lethality of the weapons systems goes up. I want 1941/1942 East Front action. I have CMBB and played some last year. But I just find no excitement with 1945 East Front. I might pick it up eventually, but I waited seven years now for an expansion to Red Thunder and they chose to make the one I don't want.
