Hosting costs and labor costs aren't equivalent to the costs of building a game from the ground up.
And no, dlc isn’t the equivalent of bug fixes and updates lol. Factorio is a great example of that - they increased the price arbitrarily and plan on releasing a paid dlc.
Paid subscription services increase because constant work has to consistently be put into them at a regular rate. There is no end point. It’s not as if a subscription server is “finished” and then only requires small updates and bug fixes - it’s a constant thing that requires endless man power and resources to keep afloat.
There’s a massive different between Netflix and Oblivion lol.
And in what world is everyone doing the same? The literal only other game to increase the price of a game over half a decade old has been Factorio. Literally nobody else, not even the scummiest publishers in the space, have done this.
Regardless, as I’ve said, it’d be more than fine if the price was increased due to an official launch, or even if they just felt that they’d added enough content to justify it. But hiding behind inflation is scummy imo, and makes me regret supporting them in the first place.
