Key figures :
$4 000 000 Kickstarter budget at least allowed to the development ($4.5m at most)
$100 000 average wage to pay ($4180 average monthly wage in Japan according the OCDE 2012 list x 24 months of development)
$4m/$0.1 = 40 permanent workers at the very least
Notes :
- I consider in my calculation that the private budget is intended to pay the potential extras like licensing, rentals, motion capture, dubbing, material, outsources, publishing, orchestra, etc.
- I consider that the Paypal budget is only a spare wheel to anticipate the possible delays as Yu seems not to care.
- It's a very rough & straight calculation, it acts like if the duration of contract would be 2 years for everyone. Infact, one programmer can work only 6 months while another can be involved during the whole 2-years project. So the number of 40 workers may increase rather easily.
- sub-teams expected : quests, events, free battle, mini games, scenario, planners, graphic design artists, music/sound artists + Sony support team
Reminder :
In comparison with Shenmue Dreamcast ( http://segaretro.org/Shenmue#Production_Credits )
- No Shenmue Saturn cost
- No Shenmue Passport cost
- No "Promotion & Publicity" team cost (role assigned to Sony)
- No R&D teams cost
- Mainly no artworks cost
