I’ve heard of video games requiring a connection to the server just to validate that the game was bought legitimately. There are games that require the internet ONLY for this. This causes problems whenever the server is offline. This would REALLY be a problem if the company goes out of business or the internet changes protocols. None of these games would be playable in 120 years, which makes it difficult to preserve them for history. There will always be a workaround created by a hacker for each of these games, but that could get lost in history.
I wish companies would stop punishing people for buying their games. Just make the game, and make it work. Any anti-piracy tactics will get broken the next day, so don’t even make me type in a serial number. That goes for all software, really. I’ve been trying to switch to completely open-source software because of all the restrictions on paid software. I’ve lost serial numbers, and once I lost the entire program AND BOTH BACKUPS OF THE INSTALLER(my online backup ran out, and I emptied the folder the other backup was in, not knowing it was there). Thankfully I found a way to restore it, because that software was a $200 value($80 actually paid, because of sales). My open-source 3D software has now replaced that animation program, AND the bugs actually get fixed!
