I've said this in other places, but I want to leave a review here, too. I've played a lot of Fate games, I've run a lot of Fate games, I've written plenty of hacked material for Fate games; #iHunt is a great iteration of Fate rules. They're well explained here, in terms that should be familiar to even new players.
The book is an easy read, unlike many RPG books. It wears its heart on its sleeve, be it while giving a no-nonsense rundown of the poverty that drives people into the gig economy or while mocking the tried and true (and stilted) "here's how you make a character!" section of every RPG book ever. The layout is crisp, the colors are vivid, and the art fits the ad-copy style of the fictional app the game centers around. If a magazine, blog, twitter feed, and RPG book had a kid and that kid decided it wanted hunt monsters and punch fascists, this book would be that kid.
This game is easily in my top three iterations of Fate. I haven't run it yet, but it's going to have a solid chance at being my top iteration once I do.
