8. Always-Online Requirements & Performance-Affecting DRM
One of the most pervasively infuriating issues of the last decade-or-so of gaming has been the increasing requirement for games, even single-player ones, to be permanently connected to the Internet in the apparent quest to "combat piracy."
Beyond online multiplayer titles, there's no good reason for placing a barrier between players and their game, given that all it does is punish those who actually paid to play it in the first place. If your Internet connection isn't great or the servers go down, you're left with an unplayable piece of software.
On the PC side things are even more nefarious, what with the inclusion of intrusive DRM like Denuvo, which while intended to prevent new games from being cracked by pirates, often ends up adversely affecting performance for paying customers.
The irony in this case is that anyone who actually pirates an affected game with the DRM removed will have an objectively superior experience to those who did the morally right thing.
Publishers need to dial back their fetishistic fascination with stamping out piracy and instead focus on making games that people actually want to pay for.
Sure, some people will always pirate regardless, but they didn't ever represent a sale to begin with, so their piracy isn't the "lost sale" publishers believe it to be.
