The other things i would suggest:
Try reaching people others including myself :-)) have failed to reach.
For example Atari UK during Jaguar era was far more than Darryl Still,Mike Fulton and Bob Katz.
Peter Walker dealt with the initial Jaguar P.R prior to it's launch and Bob Gleadow was head of Atari UK.
Same for developers..Arcade Attack do fantastic work speaking to the lower profile people who worked on high profile games.
Follow their example..
Caspain Software (just taking a UK source) were more than just Matthew Gosling, fresh voices make for better coverage as your covering ground others have attempted already on YT.
Have a read through the Jaguar section here:
Lots of soundbites/quotes/reports from the time and you'll find details of all the planned Jaguar Games by Beyond Games etc.
As for sales figures and this applies to any system,not just Atari systems...
It's wiser to present them as suggested figures and state sources that present the numbers,rather than as actual.
Your viewers are adults and given a source and a number quoted in context can decide for themselves and indeed can often come forward with sources of their own.
I honestly cannot stress the importance of using multiple sources, highly enough..You'll be asking people to try and remember events from many years ago and it's only natural confusion will Creep in,plus as we've seen, people like Jez San, Martin Hooley etc have given versions of events that have been proven to be very different to what's been found on internal documentation or accounts given by their employees.
People often forget what actually was released or being worked on for what Atari platform as Atari had such a habit of annoucing new hardware only to drop it and want people to get behind the next big thing they had planned.
Cyrano Jones doesn't need me to blow smoke up his behind :-))
His work,just as that of so many others on here speaks volumes.
Look at what he, Songbird,Piko Interactive etc have provided for the community and the partnerships they've formed with the Oliver Twins, Jeff Minter, Bitmap Bros etc..
We also have Clint Thompson with the vision of trying to build a working Jaguar Duo where as others think doing a YT video on it is equal to great vision.
If you feel you want to ask any Qs of myself..just drop us a PM.
And above all else..best of luck with the videos..that's a hellva long road you've set out on :-)
