I agree creating a whole new planet is a huge undertaking and if I were to do a full make-up for one, let alone twin orbiting planets, that would take one person more then 2 years; however there is a work-around. If I were to say create a descriptor for the planet and then and write out a specific plot line for a character that I have already created that would ease the overall workload and overall major complexities of the T.I.T.S game. When in college I was part of a 5 person team to make a mock game and trailer. We were able to create a 1 minute trailer, an one full level of a side scrolling, spaceship shooter game in 5 months. As a part of the Interactive Media Design course (graduated) I designed and animated 8 different 3D ship models, and varying other objects and scenery. I have the capability to do such work as you have described.
Admittedly the coding aspect for gaming is still beyond my reach but this form of story run, choice determined outcome game is not too far outside my reach. It is what I went to college for after all. In addition I'm a publish author working on the sequel to my first book, so writing a individual characters story is an easy yet still time consuming project. What would have to be done by some of your team is to work out the coding, and altering the story to fit the the wide variety of different user-made characters to better fit the plot line in general. I can even provide a map layout for the area and paths on the planet that the protagonist would follow using current games designs as a base.
I will gladly take your advice and write up a story for the one new character I have created to be added into the existing game-play. I am also determined however to continue with my overall original plan; even if in the end it does not work out and is not used.
To "ADMIN SAVIN" seeing that this game is part of your "brain child" I would very much like to discus my idea's and yours. If we could talk/write to each other outside of posts, I would be honored. I hope to be able to have plenty of enlightening discussions with you in the future.
Attached below is a public display of one of my ship creations (all be it one of the least interesting), a plain massive transport ship for your understanding of my capabilities. It only took me approximately 5 hours to make.
