do you think BF to be more reality?
There was an interview that Armchair General did fairly recently with Gregor Whiley (VP, SSG) about Battlefront. With respect to the question above, here's a small excerpt from that article:
ACG: Looking only at screenshots, Battlefront seems to be an enhancement of the Decisive Battles series (Ardennes, Korsun, Normandy and Italy). But the battalion level scale of Battlefront is much more tactical than DB, so it is really a different game. For those familiar with the DB series, how is Battlefront different?
GW: Many of the Battlefront concepts will be familiar to fans of the DB series. However, there are some important differences. You directly control artillery and airstrikes, picking targets and causing casualties. However, you can’t attack indiscriminately. Battlefront introduces the concept of Attack Supply, which regulates the tempo of combat operations. Only units within command range of their own HQs get the extra materiel necessary for attacks and this will often not be enough to allow attacks every turn. So as well as picking your targets you have to think about properly co-coordinating offensive operations. The new OMA scheme, outlined below, introduces greater flexibility for the player and the scenario designer. The more tactical scale introduces the concepts of Direct Fire and Line of Sight and special combat modes, such as Banzai attacks, give a significant edge to different countries when attacking.
If you haven't already done so and wish to read the whole interview, it's available right here.
