Pre-Production

For my project, I am estimating that the pre-production of my project will take up to 4 weeks so until  the 24/10/16. I think that 3 weeks weeks is a plenty of time to gather a lot of ideas for my project and also it will be enough time for me to keep on testing and learning UE4. This time will also allow me explore other possible ideas, e.g. if i wanted to make a 2d game, maybe? Also i still need to think whether I actually want to make a racing game or something else.
