I think this is probably my favorite of the Planeshifts. It's full of a lot of flavor, The pseudo Egyptian stuff can be pulled into a lot of settings, even FR.
I do think a few of the races are a little too powerful to be mixed with the regualr 5e races. The Hawkmen get +2 Dex +2 Wis, flight, and no disadvantage for long range. It outstrips other races by too much in my opinion. The Jackelmen get total immunity to frightened if they're twin is dead. The Naga get a handsfree grapple on a suped up unarmed attack. Oddly the Minotaur seems the weakest of the bunch, essentially a half-orc that trades Darkvison for horns (that are weaker than the Waterborne Adventure UA's Minotaur horns)
But honestly that's about all the complaining I got for what really is a nice bit of setting that I'll probably use.
