Ok, I think some people have missed a lot of what has been said before. So this will also go on the First Post.
I cannot model. I don't have the programs to, nor the time to at the moment. It is something I will get into, and as mentioned somewhere before, a Ring World will probably be the first thing I try, as it should be pretty easy to do. Now, responses:
@ SliderFuryI haven't seen any official time peroid until its done, so I will release 1.3 regardless, and update when 1.04 is released.
@ bandw2First, thank you for the quad-post, there is an edit button you know

. Now;
Some of your ideas have been brought up before, and are not in Sins Plus yet for various reasons. But I can answer most of you ideas with 3 points:
1. As mentioned, modeling is out of the question, unless you can model, or know someone who can model, and is willing to do work for me, for free.
2. New planets will be fewer in new releases of Sins Plus. They must be distinct and not 'just another planet'. Skins I will do, but I'm not going to pop out another 5 planets which are just slightly different from the ones present now (the Gas Giants you mentioned comes to mind).
3. I mentioned not long ago, last page I believe, that Stars have taken a back seat in this mod and will not be making a large appearance until I have all the planets up to the level I am happy with.
@ Jordanb716 & Jack IrisThe Relic world in 1.3 is not hugely dissimilar in stats to other worlds, but, its ability could make it well worth having, especially on the frontline.
I think to make an Artificial world, some degree of modeling would have to be done, so it isn't a perfect sphere and has little clinks in it, etc.
The Discworld sounds interesting, if I do get into modeling, and would definitely be one I would strongly consider. Also, it would be a nice way to portray an Artificial world, rather than a what I said above.
@ ColionAnswered in first bit.
Thank you all for the input, some good, and some not so good ideas there, greatly appreciated.
