okay, now, not to nit-pick, but the original missile defense platform i rather old-school (in terms of the fact it still has solar panels and what not)
its not ugly persay, but very spartan... and far too simplistic... i realise it still a mesh... but its missing something... i just cant put my finger on it...
also, the Human Starbase... idn, again... a bit... consternated... the shape seems weird, i think the Tau'ri have more taste than that (as in, it isnt the utalitarian, slapped together stuff of the TEC for instance, Tau'ri make things specifically, not with off the shelf components) im willing to wait to see more of it though...
honestly, i can see the Tau'ri using something that looks like the Argonev or a Star Trek Federation Starbase (though altered enough that it fits with the mod and the Stargate Universe) although i really dont want to be tacky that way...
perhaps something that looks like the current TEC trade port... large main saucer section in the center/middle, weapon banks arrayed around the circumference as well as on upper and lower pylons... hangars located in the superstructure below the saucer section... an idea perhaps would be to add smaller 'saucers' to pylon arms spanning out from the starbae with certain upgrades. for instance, a trade port upgrade would add another saucer to the starbase at the 12 o'clock position, the remote construction (if you are going to use it) would create another module at the 4 o'clock position, and repair bays upgrade would add another module at the 8 o'clock position. auxilary government (called IOA oversight in the mod?) would add another, smaller saucer module in the superstructure above the main saucer...
in general... if possible, i think a visual enhancement for all starbase upgrades would be cool, but not necessary... its up to you...
anyway,
