Yeah, I think SCAG isn't what I'm looking for. Too much fluff, and I'm going to be running a homebrew campaign, not FR or Golarion or anything like that.
I'm looking for something with a lot of crunch, or failing that, something that will help inspire my campaign, which is going to be 75%-90% "Dying Earth" and 10%-25% "Urban Steampunk."
I'm probably going to wait for the 5E version of Primeval Thule or the Tome of Beasts. Or maybe both.
Primeval Thule is out for 5e now on rpgdrivethru. Keep in mind that is mainly fluff though too although more it has more crunch than SCAG. Most of the crunch comes in the form of new and very powerful backgrounds for the setting. Also, there is some equipment and monsters too. The fluff is nicely done and novel though...much better than the forgotten realms rehash in the SCAG. My only real criticism is that while the fluff makes a big deal of how rare and evil magic is, there is no crunch to back that up. However despite that If the idea of swords & sorcery plus Cthulhu appeal to you it is a good buy.
