So, what is currently made available for modding in DW2:
- As stated in this thread, most of the game data are modifiable via XML entries which you can find in the /data folder. This includes celestial objects, research, components, diplomatic messages, troop types, facilities, and more. However, there are also some known bugs with these XML files (see forum): for example, changing a race's name causes it to be unselectable and therefore unplayable.
- You can modify ships or bases and add your own, although it represents quite a steep learning curve with Stride
- Music
- Everything editable in-game via the game editor
- "Most" above regarding game data means that there are data that remain hardcoded, such as moon properties for instance
- Any game image, including flags and species portraits
- Galaxy generation properties other than those on the game start menus, including number of stars different than those provided
- Character stats
- Game mechanics
- Sounds other than music tracks
