Have been away the past days, sorry for the late reply.
Just want to point out that you can arrange SBP to not use the modern techno-gimmicks like laser-range-finders, thermal imagers, stabilisation etc, and do it with WWII-like secondary optics and manual range finding, very much giving you the experience of fighting the way our grandfathers did. That way it blasts big holes into WWII-titles while avoiding to give you the high fidelity electronics of the present. you use weaker ammo, and some of the less heavily armoured tanks.
The engine power however still sets it apart from WWII.
