Even full expansions in many cases are being called DLC on Steam.
That was, not so long ago, the definition of DLC, i.e. substantial map and story expansions, etc. Unfortunately, the gaming industry, kissing cousin of the tech sector, has normalized the idea that anything requiring download in addition to base game assets (thanks only in small part to BGS' infamous horse armor) is "content." Ntm, the present push for a gaming "metaverse" and subscription "services". And, once again, marketers and propagandists whose job it is to render words meaningless have succeeded in gaslighting the public into believing they're getting value for their money when purchasing virtual "assets" (generally retextures and recolorings) that are not only not tangible and won't last, but took mere minutes to accomplish in a software program like Photoshop while upward of the price of a full game is being charged for them.
There is a movement among artists of all kinds to stop use of the word, content, in reference to artistic work requiring a substantial amount of time, energy and talent to produce and I can see why. It devalues human creativity. Alas, few are bothered even by the fact that the tech sector presumes AI will take over for us in that capacity.
I'll not argue for or against insubstantial "paid DLC" or talk of "slippery slopes" and just hope people with more money than sense will come to their senses eventually and stop allowing themselves but, especially, their children to be bamboozled.
Obscenely greedy industry practices are ruining the hobby of gaming and game modding for many and most just can't quite seem to put their finger on why it is they don't enjoy it as much as they once did. I'd hazard to guess the real reason is that they're exhausted of having to defend themselves, psychologically and otherwise, when playing a video game. We can't just sit back, relax and enjoy one anymore. Nope. We have to protect ourselves and our families from ever-more egregious industry practices, machinations and manipulations.
