Creator Jobs :Me (Linkguy) I'm doing MainMenu Moding, Load's and thing's that is not to be told about yet 
General is doing MapModing
So... it has no current features apart from a few extra maps which could be released as Add-Ons, a few generic saves which could be released in the Gallery and a FLASHY NEW MAIN MENU which will annoy people?
You might be thinking "Hes copying those mods..."But what came first? RTB or TBM one of them came first but they did'nt copy.
Correct. RTB and TBM did not copy the idea of making a game-adjusting mod. However, that isn't relevant. You appear to be copying their idea.
This post is yet to be unfinnished and we will add a few more thing's like the pictures and the download for the i-Mod DEMO and the i-Mod Full Version
I don't think you can charge money for mods as the license you agreed to when installing the game says they are all property of Badspot and Step 1: Games. I can't see any other "features" your mod could have which require you to make a "demo" version of it.
