...It seems I've instigated a riot. Sweet!
From when I first heard of and saw the Z-95, it always had these features:
-Four engines. Always. On a single, non-moving wing.
-A bulge behind the cockpit for the hyperdrive motivator, or something like that.
-A bubble-like canopy. Lucas Arts seems to have added progressively more canopy framing over time - no idea why.
The Z-95 that the XWA Upgrade Project has (linked to previously) is pretty much the most faithful rep for the fighter I've seen, despite its comparatively low quality. I think Totally Games did a superlative job in the early days of keeping details/aesthetics right, even when they were dealing with really low poly-counts. That was compensated for with additional material supplied with the games.
Now, if there is one thing I can cite that's a problem with the older DReim Z-95 that the new one covers well is the lower fuselage shape. The Z-95 always bowed out on the bottom, and my preferred version has a good looking, albeit wrong, serpentine profile. The angularity of the fuselage in key areas before the wing is one thing the new model does pretty well - the older one would need a touch-up in that regard.
