Few games can aspire higher than to be a clone of Independence War, don't see what the complaint there is. Unless it's the evil evil I-War 2 you're thinking, which is evil and should die and not be imitated in the least because it sucked ass and was a puzzle-based game. That's not personal taste, that's the truth- it murders Christian babies and sells their captured souls to Satan in exchange for puppies to torture and drown.
Anyway. Gotta agree on the curves bit- I dig blocky, too. But a lot of the models seem to be lacking a certain something... there's no really consistent theme, near as I can tell (nothing similar at all between the fighter Carl posted and, say,
this except that I don't like them), so the focus should really be on just having a large variety of cool-looking models. That one you posted being a good example- it's got a coherent, vaguely recognizable design without being so generic as to bore everyone to death. More like that, less like the other two, and a
lot of variety in the forms the ships take would probably be the way to go there. As it is, they're pretty spotty, with some good 'uns and a lot of models looking like they're just five-second placeholders until something more complete can be put in. You don't need a lot of polygons to make a good-looking ship, even- just good textures and an interesting shape. You don't need to make it curvy (though a few curved surfaces for variety wouldn't hurt), there's plenty of room in the "big 'n blocky" category. And some models that didn't look like hastily-textured fighter planes and spraypaint cans would make me twitch
so much less, especially given how much else is just plain cool, graphically and otherwise, there.
Incidentially, you ever want help with models or something, I'm game. Just, you know, in case.
