I know, it’s waaaay to early for this stuff (it’s an early alpha after all)…
But browsing through the gamefiles showed some (kind of) easy modding options for this game. I managed to add another upgrade for the cars, a gold-frame (because why not ) with some easy modifications to the gamefiles. But the next patch will certainly revert everything back to the default upgrades.
So here my suggestion:
Add something like an overwrite folder to the game, that can contain modded files. When loading, the game skips the original files also present in the overwrite folder.
Or the game could merge files with identical names.
