Rise of the Ronin is an adventure of substantial size, but whether it's possible to keep playing after the credits roll is one question that's likely to come to mind over the course of the game. As an open-world experience, Rise of the Ronin has plenty of side content that could be passed over while racing toward the story's climax. The game's developer Team Ninja included a variety of optional missions in prior games like Nioh, so it's no surprise that this element carries over to the more expansive historical setting of Edo in Japan.
