Well, so far I have been trying to check if I can modify different text, mainly the quests are easy and some interactions such us the 'press E to speak to' is kind of easy. Also been able to modify the settings but haven't been able to change text that is in TextMeshPro (type of settings or all the main menu interactions)
I am making this project as a way to support the comunity and im my free times, so I don't know how far it can get
Also with my low knowledge I still don't understand how to change dialogs, mainly becuse I search for text
Finally one of the biggest problem is that I don't know were to look for the data (So, even if I would like to change the main things first because Im using an Unity game modifier (Dnspy) I just change wharever I first encounter
So far I have benn able to:
Translate all settings except for controls
Translate the interaction key
Translate a few quests like Hogan and Ingot (Oly the quest names and description)
And I am trying to change some bosses names (I will leave mosters the last because their names are so wierd that seem language from the space)
Regarding to your modding problem, I think so far people will have it easier to overwrite data than adding new one
Also, do you know where to upload the patch?
