Most games that are long are artificially so, with padded out content and grinding to advance. Short excellent games sell well. Huge expensive messes don’t.

Just like movies, large blockbuster, high budget content can sell well but does risk sacrificing its soul and purpose. Occasionally one is both excellent technically, artistically and fun too.

Or you can have smaller games with a more specific purpose which won’t sell as well. Some low budget games are bad. Some high budget games are bad. Neither is a mark of quality, they are just different ways of making games with different outcomes and purposes.

Games need to turn a profit to be visible, so they should be looking at what’s the optimum way to spend their budget and make sales.

As gamers, we should be rewarding good games, and avoiding microtransactions and all the upsells. I don’t buy any cosmetics or additional content (unless it’s a continuation of the game that makes sense as another chapter). I want to avoid that side of gaming as it doesn’t lead to good games. I pay full price at launch for my favourite game series, but not extra content. Other games I purchase later on sale.
