It's unfortunate that other developers don't follow this sort of business model - the industry as a whole is definitely going the wrong way about things, charging a decent amount for random bits of DLC, often things that should've been on the disc to start with; add in DLC that you have to pay for and gives you an in-game advantage in multiplayer games and things start to become pay-to-win; which as far as I'm concerned ruins a game, and is a terrible business model that the vast majority of real gamers hate.
Honestly, I don't even mind paying for a good size expansion pack, provided the price is fair; but paying £1-2 for tiny things for which the right price point would be literally 1-2pennies/cent is out of the question, such things should be free, especially if they could potentially damage game balance.
Sadly, exploiting gamers really is the right word at this point - game prices themselves might be fine, but they're plagued with DLC/microtransaction style things that effectively rise the price so far that it's not even worth buying any more.
As much as people like Jack Thompson would disagree, gamers still have morals and we're intelligent enough to realise that we're getting ripped off on many things - sure many will buy them anyway, for a variety of mostly not-so-sensible reasons - but it damages the public opinion of the company when there's other smaller companies like CDPR (many things, such as noted in the article) and Runic games (actually allowed piracy of their game openly at the start, did nothing to stop it, and then many people went and bought the game after trying out pirated versions and game updates coming out - most the people pirating games are the ones that wouldn't buy it anyway if they couldn't get it for free, while others try out a pirated version as a sort of demo, either way, if the game is good it hugely increases positive word of mouth for the game, and in turn raises the amount of sales, with even many of the people originally pirating the game buying it in the end when it went on sale) that have gone away from the grain and profited as a result.
Honestly, it seems as though many of the larger companies aren't really in touch with gaming at all, and are just in it for the money and nothing else nowadays, which is disgraceful, and is slowly taking the industry in a terrible direction.
