Just wow, Pixar quality porn game.
Sure, as expected from the demo the gameplay is clunky, world isn't interactable and scenes break gameplay flow and are forced pov, but seeing the lively FC animation when captain came just hits different. Definitely looking forward to seeing how this one goes forth. It definitely has potential to become best R game of decade.
PS: For people who don't know ~5gb is default size of Unreal projects with starter template. Once unused assets are removed and large files are compressed, the size will go drastically down. But for demo there is no good reason to waste time with optimization. And of-course as the project grows, the amount of assets will grow with it making this point about template size null. But that is the reason why most new Unreal games in this site are +5gb.
