The second comment to that article speaks volumes:
"That's because a large number of big AAA releases in this day and age are designed to be disposable.
Most publishers don't want you to buy a game and play it for years to come. They want you to pre-order the game, buy the season pass, buy the loot boxes…then turn around and do the exact same thing with the next iteration a year later. The game you bought last year and pumped so much money and time into was never meant to last for more than a few months, and was designed to hold your attention only until the next one comes along.
There will always be handfuls of people who prefer to stay with ___ version of a particular game, and the servers for said game will eventually get shut down and that sucks for those people, but the overwhelming majority are only interested in the new shiny thing."
…and thus we have the clear picture of the model that certain tabletop game makers are also invoking. Sure, among your friends, you can dust off that 30-year-old ruleset and have a game, IF you've all got the figures and such. But our current game market is so flooded with options and choices – which in itself, is a pretty darned nice thing – that time and attention are the true currency by which money is to be made. When so many tabletop games require a pool of local players to generate interest and action, it becomes a big competition to fight for and keep their attention – you can want to play AD&D or DBM or Ogre or Laserburn, but that thing that is Cool Thing Of The Month is going to capture more people's attention and too quickly leave one with the choice of playing the month's flavor… or playing solo.
And thus the cycle of Forced Obsolescence keeps the churn going. For video games, the evolution of computing power is a factor, as new techno toys simply can look better and offer more comprehensive experiences than the ol' Atari 2600 ever could. Of course, you can still play Yars' Revenge, but if you didn't grow up playing it… why would you now? For tabletop games, this churn comes in the name of fixes and rule updates, but instead of patching something up… heck, why not just throw out the old, and demand that everyone buy the new if they don't want their collections to become a Dustbunny Army overnight?
So, more and more as it is with video games, the more choices we have, and the faster we can disseminate product news, the harder it is to get someone to play the game YOU want to play, without riding this wave an ponying up for The New Thing.
From one very potent perspective, we're in a very wonderful and golden age for miniatures games. Even the most hardened cynic can find something cool out there in the incredible number of options available; I know I can't go a week without seeing some new figure that immediately gets me to check my bank account. But as it is on the Internet, attention is itself a hugely valuable commodity, practically synonymous with money, and it is the lucky gamer indeed that can remain unaffected when there are just so many options that only the current wave of hype and shine can bring people to sit around one table and play one game at a time, even if they gotta buy that new rulebook to do it.
