The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
Pretty damned impressed too, from an initial glance. Wasn't planning on making the switch from 3.5, but I have to say that I may just have to reconsider that. It looks like converting existing 3.5 material will generally be easy and the changes appear (at a glance!) to be pretty good on the whole.
Need to read it in a lot more detail first, though - but first impressions are very good.
