From publisher blurb:
Welcome to the Retroverse!
An exciting new 5E universe from Lasers & Liches that resides in a place of half faded memories, barely remembered songs, lost childhood friends, outdated styles, abandoned dreams, lost playthings, vapor ware, and time corroded nostalgia. A place both strange and familiar. A place for adventure, friendship, chaos, and the magic of yesteryear. In short, a place that combines your love of the present with your adoration of the past.
The most recent update (V4) adds the long-awaited Datamancer class! There have been several changes to other classes and many bug fixes through the whole game. A handful of other things have been added, like new weapons, a trinket table, a new feat and cliche or so, and a bunch of fun new art!
