The ending: Lan Di gets away again, Ryo spends a few hours wandering in the woods with Ling Shenhua, and then he discovers a magic sword in a cave. The sword floats, magically. We get no explanation as to how magic is now happening in the resolutely realistic world of Shenmue, and moments later the series inadvertently ends.
The ending we'd attach: Shenmue II's new ending would need to do two things. Firstly, it would need to resolve Ryo's journey of revenge against Lan Di. Secondly, it would need to explain that bloody magic sword. The answer? Just throw all semblance of reality out of the window (like the game hasn’t already done that by this point) and go full-Dragonball. Ryo grabs the sword, does a loud, flashy henshin transformation, flies through the sky (ideally with speedlines) to wherever Lan Di is and skewers him from the clouds. "Thank God you found my magic sword”, he says to Ling (who for some reason is also there), “That would have taken ages otherwise"
"I know, seven discs already, right?" she replies And then they'd both laugh, and the image on screen still-frames as the credits roll. Tell us that wouldn't have been better than the last 12 years of waiting.
