I am going to be honest about this, and ive had this discussion earlier today with a few others.
You are more than free to try and get people to increase their pledges, but the Dojo as a brand will not be taking part in any campaign to try and get to "7 million".
Whilst its a nice round number, at this point in time, our focus is now to encourage sales of both the re-releases and also of course, Shenmue 3. The problem is the more copies of the game that go through the PayPal avenue risk the number of people buying the game at retail, and at this point, that's not what we need. Shenmue 4 is dependant on retail sales alone. Its been said numerous times, and if someone uping their pledge to get another copy results in them NOT buying a copy at retail then there's no way i can support that.
Crowdfunding has gotten us to where we are now with Shenmue 3, and it has indeed #savedshenmue. But its done. With additional funding from Shibuya, followed by Deep Silver, the development timescale for this game would have been locked in, and any projections for in game mechanics such as the 7 million dollar AI Battling system would have either been included, or dropped depending on those factors. With Shenmue 3 more or less a year away, i would also doubt they are going to edit the entire mechanics of a big part of the game all because there was a push at the end.
Do i think AI Battling is already in the game? Yes is do. So my advice would be to not push for a simple round figure that could jeopardise Shenmue 4, but wait until the Slacker Backer campaign is over, and then push people to buy both the re-releases as well as 3. Those retail figures are what will make the most difference.
