We did do it once, but the number of voices that lent themselves to that campaign were much larger then. I just don't think there is that same lust or fire that there was. A lot of casual voices lent themselves to the number requesting Shenmue 3. It had become almost symbolic or something, it was like Half Life 3 and other unreleased sequels, with there being a mystique to it. There was a snowball effect, where a bunch of casuals (or even just people who played one or both games back in the day but weren't necessarily huge fans) jumped on board. I remember on forums back in the day "we want Shenmue 3", "Sega, release Shenmue 3" was practically a meme. All sorts of casual gamers would namedrop it as a game they wanted.
If I sound negative, it's because I am. To me, the path to securing the franchises future was laid upon us when the Shenmue 3 Kickstarter was announced. That was Yu Suzuki's moment and our moment. That was the time to save Shenmue. They and we needed to prove the demand and then prove that a Shenmue game can be a success, so that a publisher then comes on board to ensure the franchise continues. So yes, the fact that they/we failed on that does depress me. The fact that we have to fight for a Shenmue 4 depresses me. Even more so now that "we" basically amounts to a meagre number of fans left on a few social media groups and forums like this. It's not like there's an army of fans clamouring for the 4th game. If no publisher cared in 2020, or 2021, or 2022, or 2023, then realistically I don't really know what people expect to change in 2024 or beyond that will make one suddenly jump on board.
