The problem with certain content is that it can lead to all sorts of legal problems for the site, that said a 18+ section could be added for such things as a compromise.
The same rules have always applied to Starbound Mods - as you can see most users still use this site for downloading Starbound Mods even though other options are available. So based on historical facts your assumption would not be the case. New Games can easily be added to Nexus by simply using the Wizard Tool. So the only reason it is not there, is because no one has done it yet.
Just to clarify, the game will be available on the list once a mod for it is uploaded. That's how the site works.
Hey mods, you guys want me to use a more conservative name and make slight adjustments to the Penny mod?
We are currently discussing the issue with Molly - so we will have a more concrete answer after a period of time.
From what I've been seeing on the /vg/ thread I think Randy is in the course of re-releasing them. I'm not 100% on that though so I'll drop you a PM with the mega files.
@Afterscore Ditto, for science, i need the "REDACTED" Versions, for science you know. Would be appreciated.
Of course, how can I refuse a member of the scientific community a chance to further his knowledge of the field.
This is so... omg. Realy? I mean, a spoiler would do this job if the mods realy thing this is to "adult" (pfwahaha, sry, can't say that without laughing). Its just a cleavage... a deep one, but just a cleavage. i mean... c'mon... realy? I could understand this if there would be "more" to see, but there is non!
On a different note, when can we expect a bodybuilder mod for the dudes? Or one that makes the player character as buff as old timey Arnold Schwarzenegger? That would be enjoyable.
