The Kickstarter campaign for Shenmue 3 is now 38 hours away from being done, and developer YS Net has gotten impressive $5.1 million so far. The game will be available as a physical copy on PlayStation 4 for any backer who donates a minimum of $60, but it's far from certain that the game will end up i the store shelves.
VG247 has reached out to YS Net regarding physical copies, and the developer replied with "Whether Shenmue 3 will be available for retail or not is currently unconfirmed".
Consider yourself warned, should you be one of those who prefer physical over downloaded games.
