Well, I played steel beasts (the old version not the PE). While it was, and still is, a superb tank simulator it do not play in the same league as combat mission do. While they share the cold war gone hot theme, I believe they are not comparable.
I think Battlefront CM is a platform adaptable enough to cover any time period from WWI to near future (Black Sea). I maybe just find the 1950-1990 gap missing. As I said, Euroscape devs tried to but hit the wall with new models (can mod a M1A2 to look like a 105mm M1, but it will still send out M829Ax ammo)
Thats one of those ocasions where DEV team and MOD teams could work toghether to create a WIN-WIN-WIN (for players). Of course the resulting "pack" will be paid, but for a little DEV work (mostly compiling models already done and adjusting data to match 80s reality) CM can have a completely different theme.
Let's do a thing, for anyone who would want a Cold war CM, post the vehicles and infantry teams you would want in the pack, so we all make like a wishlist.
