This is just another Playtracker or Steamspy.
They use public data, like number of reviews, follows, concurrent players and take leaked or officially announced sales numbers to do some regression analysis on future sales.
However, its likely a poor regression analysis, as there simply isn't enough real sales data out there, unless you simply get the answers from NPD/GSD.
Not only that but they would need data across every year, as the Steam userbase changes and so do the coefficients.
1. BG3: 13.5m
2. Hogwarts: 7.5m
3. Starfield: 4.5m
4. RE4: 3.7m
5. SoTF: 5.2m
6. AC6: 1.8m
7. FC24: 1.9m
8: SW Jedi: 1.3m
Those numbers look very wrong.
As you can see, from the Valve playercount leak, RE mainline has a 10-15% PC to total sales ratio.
RE4 should be around 6M+ by the end of the year. 3.7M coming from Steam is hugely wrong.
UK charts had Steam at 15% of monthly sales.
| Title | Capcom Platinum sales June 30 2018 (M) | Data from Valve playercount leak July 2018 (M) | % from PC |
|---|
| Resident Evil 5 | 10.9 | 1 | 0.09 |
| Resident Evil 6 | 8.6 | 1.3 | 0.15 |
| Resident Evil 4 | 7.1 | 0.7 | 0.10 |
| Resident Evil 7 | 5.4 | 0.67 | 0.12 |
Also tried comparing the recent Sony PC leaked data to VGI, but I think they are updating their sales "estimates" once public data gets leaked or announced, like what VGChartz does, so they aren't being transparent in their accuracy.
We've had one recent sales number:
Deep Rock -
8.38M all platforms
VG Insights -
8.06M just Steam
Steam looks to be 70-75% of daily concurrent users
