Crowdsourcing still relies on copyright usually, and does in the cases you mention. It's simply preording a game or a book. Without copyright there would be no need to preorder the game or book, you could simply wait until it is out and make a free copy of it.

Both Obduction and Firmament are for sale. They aren't free games.

There are plenty of freely-available works that are crowdfunded though. It's true however that the costs of making a game like Obduction and Firmament dwarf even those crowdfunding revenues. The same applies to high-budget feature films. A 100% crowdfunding approach strongly selects for lower production costs, which also means improved efficiency and a larger variety of works overall.
