i think just building the stuff gives you more appreciation for the work others do.
after building maps and seeing how much work goes into them i dont critiscise anyone elses map.
I see how much work building 3d models is and how precise you must be to get accurate and good looking aircraft is not easy, any line just slightly out of place ruins the proportions of the model!
i think part of the fun for the designers of the targetware games and playing them as well is that they can create these planes and go fly them against other players.
as far as being a waste of time building 3d models, well who knows, I was pretty bumbed that no matter how few polygons i use or how accurate i make that liberator its never gonna fly in aces high, so i crashed and burned in that regard and it would seem my efforts to that end ar eindeed a waste of time if you want to look at it that way.
but considering i started the b24 as a practice model and it started looking good o i thought hmm maybe its usable. the up side is a few days ago i didnt know how to build a 3d airplane, or how to use 3dsmax hell i didnt know what splines meshs welds fuzes or any of that crap was till i started this experiment. well in that regard it was not a waste of time.
i dont think the effort the designers put into targetware games are a waste no matter what the outcome of the games in terms of popularity.
