undertale:

There were a few reasons I instated this policy. However, after talking to a lawyer, it seems like allowing certain things won’t really hurt Temmie or Fangamer (my friends). So things will become more lenient.

Now, I won’t stop individual fans from selling the following items at cons:

– Prints, charms, buttons, keychains, stickers, etc.
– Most handmade items
– Undertale zines/fanbooks/doujinshi
– Musical albums/CDs that contain UNDERTALE remixes as <=30% of tracks. (Still figuring out full albums…)

However, restrictions exist:

– You cannot use the UNDERTALE logo or put the name UNDERTALE on it, as it is trademarked. (Weird, right!?)
– No t-shirts, apparel/clothing,* or machine-made figures or machine-made plushes.
– Do not sell merch via Redbubble, zazzle, or other large online store.
– No, you still can’t do Kickstarters or crowdfunding campaigns for UT-related things.
– If you’re a company (like Sharkrobot or Hot Topic or something) you cannot sell UNDERTALE merch of ANY kind.
– Do not compete with official merch & acknowledge my copyright. If necessary, I can halt any unofficial item’s sale. (Really don’t want to ^^;;)
– If this change turns out to be actually bad, I can reverse the decision.
– If you sell, please have played the game.

* Exception: if someone hand-made a few scarves, hats, cosplay, or accessories, it’d probably be OK. But if mass-produced, it could become a problem.

When in doubt, if hand-made and few, it’s OK. If mass-produced and machine/factory made, it’s not OK.

PS – One-off art commissions of UT characters are still OK, online or offline.

PPS –
If engaging in UNDERTALE activities at a con (selling, cosplaying, etc.), try to be respectful and give a good impression. Overall, UNDERTALE’s had a positive effect on people who have played it. It’d be nice if it could have a positive effect on the rest of the world, too.
