Bobby, sometimes I think that with all due respect to Ares neither are they... Hull damage makes sense at least, it's a straight mathematical conversion from British tonnage BM IIRC.

What doesn't help is that while WGF and WGS are relatively "Open Source" in how they've converted their stats... while they both use cards for movement and chit or card draws for damage, comparing SGN to WGF/WGS is like comparing Windows to Linux in terms of "source code" accessibility.
