I tried running JFDuke3d with them and I just got CON parser errors with them. Maybe the engine was modified to allow lazy coding syntaxes.
You know, up until that comment I didn't really think you were clueless. As someone who works daily with what was once the WW2GI code, I suppose I shouldn't take offense -- you simply don't know what you're talking about. However, it's still quite disconcerting that one would make such a dull comment without having done any research on the matter whatsoever.
WW2GI is
drastically different from Duke3D and there are easily more than 20,000 lines of differences in the source code. I'm pretty sure WW2GI would run with EDuke32, but the weapons would be a bit messed up as I ripped out all of the #ifdef surrounded WW2GI specific code a long while back. If someone wanted to, they could code an EDuke32 mod that ran the WW2GI data and handled weapon display via the CONs with little effort.
