The VOIDRUNNER'S CODEX is LIVE! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
Look on the bright side - as long as you haven't received it, the rest of your d20 collection will look good.
Once you get the WLD, all the other d20 products seem lacking....
(At least they do for me.)
The nice thing about the WLD is that it's so loaded with adventure, that you almost don't need any other products (except the core books) to have fun playing D&D for years.
I'm sure you are spot on with that one. I don't own any d20 products (other than dual statted books), but the moment I laid eyes on WLD I knew I had to have it.
