Released not long after the world had heard about 4th Edition, Tome of the Lost Realms does what Pathfinder also sat out to do, extend the life of the 3.x ruleset. Also like Pathfinder, this is a massive book at near 480 pages. The fonts and typography are meant to bring another Realms to your mind I am sure. The realms themselves are interesting as far as that sort of thing goes. the races section is rather large with all sorts of fantasy races, again many we have seen before. The same classes as 3.x/Pathfinder, with the Warlock replacing the Sorcerer in all but name. There are skills, feats, equipment and spells just like 3.x but it is hard to tell if anything here is new or not since there is so much of it. The Section 15 of this book leads me to believe that there is a ton of stuff in this book above and beyond the SRD, but nothing jumped out at me.
In the end this is 3.x or maybe 3.6. It is not quite Pathfinder and it has not moved past it's D&D roots to be completely unique either.
I gave 3 stars out of 5 since there is nothing really new here. But the price puts it at a fifth of the cost of Pathfinder, so maybe 3.5 out of 5.
[3 of 5 Stars!]
