Thanks for your very detailed reply,
Unfortunately I am a Software Engineer,And i Love the game, i make my own mods if i need.Enjoy the game far more than I thought.
Reading your reply I'm very disappointed.
RSS + RO is a great mod, made by unofficial developer, that earns barely any money from it. I dont think the modder Has more resources than KSP Dev team. Its not about excuses its about love and Passion.
When i bought the DLC I just realized KSP is shifted from making a great game to making good money. But if RSS comes out as another DLC, I'll buy it.
To answer the things you point out, i might give a solution.
first you dont design planets you generate them (noise generating, texture generating and such).
re-balancing parts is also not that bad, you can make a re-scaling of parameters and use it for every related part so you wont need do once per part.
Its just parameters to scale. KSP has a Gravity hack in F12 menu, everything is just like that, scaling up to needed value.
I suggest this for official ksp team is because RSS in not supported on 1.6 . Besides its a suggestion, its a wish and passion for the game. you dont have to teach me bunch of stuff that you dont understand yourself,you have to work on that 25 years of experience.
I just hope to see such a feature since its a space simulating game.But hope is not reality, there are mountains in the way.
we're done here.
