Is Star Citizen at all moddable?
You know, that's a question where there's more to the answer than one would think. I mean, sure, we can just answer that with a "no", but there's more to the tale.
As things stand currently(!), pretty much any kind of modding is against the Terms of Service. However, back during the Kickstarter phase, which started almost ten years ago (2012. October), they promised both self-hosted servers and modding support. Looking at the page now, it currently says:
"
Our modding tools will allow players to design new ships for both submission to the persistent RSI ship dealer network or to build custom ships and items for the self-hosted multiplayer mode."
So, according to this, one would expect modding in ships, items, and being able to host servers (of some mode) yourself. There is more promised, however. The store page actually has an
"Engineering Manual for Modders" available for pre-order, for merely 10 USD plus VAT. Now, the description for that one is:
"
This one goes there, that one goes there! Learn the ins and outs of modding Star Citizens’ private servers with this helpful guide. Want to create your own ship, modify a game mechanic or build your own planet? Look no further! (Digital version)
Note: This is a pre-order and won’t be available until closer to game launch."
So hey, not just ships, but you can also mod game mechanics and add planets! Sounds great, no?
Well, no, because years later, someone from CIG (I can't remember who, and I'd rather not wade through the myriad videos to find the one) said that modding support is at the bottom of the list, and it will only come well after launch.
To sum it up, the extended answer to the question is: it isn't currently moddable, and it's only going to have rather limited moddability (trying to bake mod support in after launch pretty much guarantees this), but only at an unspecified date - likely in the distant future.
Impressively enough, CIG have managed to find a way to squeeze some money out of even this.
