With some time to reflect on it... I'm reminded of the DRM in Civ III, which was not as controversial as Denuvo, but which did wind up causing issues. You can read about it on this thread:
https://forums.civfanatics.com/threads/civ-3-windows-update-kb3086255-safedisc.552308/ But the most important part from a "general consumer" standpoint is:
Beginning with Windows 10, the secdrv service can not be run or installed on a system so any older games that use these programs will no longer work. Additionally, with the September 2015 Windows Security Update KB3086255, the service has also been disabled on older Windows OSs (Vista, 7, 8, 8.1), causing these games to no longer run on these systems either.
Now, obviously, people are still playing Civ III today, so what gives? Firaxis released Civ III on Steam and GOG, without the SecuROM DRM, or any other form of DRM (unless you consider Steam itself to be DRM, which at least the way it is implemented in Civ III, where the game runs just fine without Steam running, I do not). Thus, anyone playing Civ III today is playing one of:
- Steam Civ III
- GOG Civ III
- The original CDs on Vista or earlier, or on 7/8/8.1 without the KB3086255 patch
- One of the rare disc-based versions that did not include SecuROM, such as the Civilization Chronicles disc
Civ III is only $5-$6 on Steam/GOG, and was back then too, so it wasn't a huge deal to buy a DRM-free copy(some mod incompatibilities with the Steam version are due to a separate bug with the Steam multiplayer implementation). But it's still an inconvenience that wouldn't have happened without SecuROM; if the discs had been DRM-free, in all likelihood you could still play with them on Windows 11.
You may think, well, Denuvo is fairly established, this is unlikely to happen with it. The same thing could have been said of SecuROM in 2001, though. By 2015, it was no longer supported. And while yes, 14 years is a long time, Civilization games tend to stand the test of time.
Thus I think long-term, one of the concerns this raises is, will Denuvo be removed
eventually? Firaxis's track record is not bad here; Civ4 is also available on GOG nowadays. But as others have mentioned, the problem is probably 2K here. They see an opportunity to maximize $70-$130 first-week sales, which does kind of make sense. For those of us with a twenty-year horizon, though, it's concerning.
