Star Trek Adventures bundle is the first wave or so of products. $240 of PDFs (retail price) for $18. There are various bundles so the retail price is closer to $160 but $18 is a great bargain. I don't own $30 of it, $40 if you count the Starter Set.

But eventually I want to buy the Admiral Bundle which is every product in print at about a 40% discount. As the bundle is updated you can pay the difference to get the new items which means the Humble Bundle is not part of it since the products are delivered via Modiphius not DTRPG. For simplicity I'll pass on this bundle.
