if crap=old techniques used to get around hardware limitations at the time (take a look at 2d trees in n64 adventure games), then it is. having a models file for weapons allows for some creative element, sice your not limited in what the shape is either. to put it simply, the autogenereated lasers arent fitting in with all the new stuff. the subach can be a very nice looking laser, instead of a strecthed out pink thing. take a look at lightspeeds version....

even thought its a retexture, it just shows how much you can upgrade the look of weapons. now imagine thats as a model.
