The Humble Cryengine Bundle is an interesting mix of games, and resources that could help you make games. The $1 entry tier gets you Rolling Sun, Aporia: Beyond the Valley, and The Land of Pain, all games; and Cryengine V Samples, Cryengine Webinar Training Videos, and the Crysis 3 Animation Pack—not the game, the assets. Crysis 3, sadly, is not part of this package. 

Ryse: Son of Rome is in there, however, along with Miscreated (in early access), Sniper: Ghost Warrior 2, UAYEB, the Snow Pro Pack DLC, an Underwater Demo level, a Robinson: The Journey asset pack, and the Ryse: Son of Rome asset pack, all of which are appended to the previous for beating the average price. And at $15, there's also Sniper: Ghost Warrior 3, Homefront: The Revolution, the Deceit asset pack, and The Climb asset pack. There's some World of Warships loot in there as well, a couple of soundtracks, and a coupon for half-off Robinson: The Journey.
