Sorry for not posting previously, (I haven't had as much time to play as I'd like over the last few days). I liked the look of your designs enough that I downloaded them. I haven't yet had the chance to use them in game but that's my problem and not yours, I should have posted something and not just dl'd. Your work is an interesting counterpoint to some of the other work being done on Avorion ships, where the aesthetic seems to significantly outweigh functionality. I like the fact that you've approached the problem more from the utility angle with the upgradability of each ship being a significant part of the design philosophy, making that your unique selling point, if you will. For me this is important as I always end up looking for more from ships after a while, more room, speed, energy, etc, so the fact that I have to spend less time doing that is pretty cool.
When I look at them again I'm even more impressed by the fact that you've done the work to make them relatively easy to upgrade and they've still turned out looking like ships, whereas mine have had a tendency to look like something a five year old with the attention span of a gnat would make using Lego.
Keep making easy to upgrade ships, from a practical perspective, they're just what the doctor ordered
