I have been modding games for ages, and the next step seems to create simple short game experiences through experimenting with mechanics. I am not an artist or a writer, so my stuff is not visually stylized or made to tell a story.
4x games are massively complex, and at least for me very rewarding to master. Typically I would just try and mod in what I want to see, provided that it was possible to do such, but the next step is to build one that is as moddable as possible. Since I don't care for generic alien races I decided that the races and ships could be left out, and added by mods. The project is free, and anyone could potential help with finding bugs and making new features.
I created a less than impressive game around the TV/toy line of Beast Wars: Transformers back when UDK was first released. Here is a link to the 3d models I commissioned an artist to create for the project: https://bitbucket.org/McShooterz/beast-wars-fan-project/src , so any other beast wars fans can use them to hopefully make something decent.
