SPWaW could likely be modern, but then again, SPWaW was built from Steel Panthers 3 Brigade Combat which had modern scenarios for it.
The problem is the software is designed differently.
The SP Cammo group differs in design preferences issues though (it's why there is SPWW2 and SPWaW, there was a split in the individuals visions of the better game involved).
I am sure if SP Cammo was even remotely interested in making SPWaW into modern, they would never have spent the time making the update to the original Steel Panthers 2 Modern Battles.
All things considered, SPMBT is a fine modern version. There is very little reason to fuss over making SPWaW into modern.
SPWaW differs from SPMBT in a few ways, but not enough to merit a person killing themselves over it. By the time Matrix or anyone could make SPWaW into modern, they could just as easily give us Combat Leader modern (which we are all awaiting for at any rate).
I LIKE that my life bothers them,
Why should I be the only one bothered by it eh.
