"[Question #1] Steel .... : Kharkov 1942" or something. I did not know this game.
Steel Fury:Kharkov 1942(SFK42) is a Tank simulator only,while Achtung Panzer Operation Star(APOS) is a tactics simulator only.
Steel Armor:Blaze of War(SABoW) is a modern warfare tank simulator also much like the game SFK 42 and is based on WW2 tank combat.
Hopefully,one day we will have a modern warfare tactics simulator like APOS for this Graviteam family of games.
