Pcm92, I am sure that if you actually PLAY THE GAMES, then you will finally wonder why there is not a Shenmue III. Shenmue II was left on what you might call a cliffhanger. There have been many statements as to why Shenmue III would not actually work.
1. Budget.
This is probably the most common response. I think it would cost about as much as any other Sega game, and most of the games they have been making lately have not sold much, so sales should not really be a problem either.
2. Interest.
People might not be as interested in the Shenmue franchise as they used to be. That does not mean anything as to their interest in the future. Street Fighter:2 was a success. Most people have never even played Street Fighter:1. I am not sure if there even is one.
3. Modern technology.
Actually this is more of an advantage, so I am not sure what people were thinking with this one. I mean, graphics and download content would be amazing.
There would be no other Sega game better than Shenmue III. It would be the greatest Sega release of all time!
