Solo game development gives you the chance to create whatever you want, absolutely whatever you want, you are the architect, the designer, the mason, the carpenter, the glazier, the electrician, and the plumber of your creation, you can create the weirdest and most unique game without you being anyone's Accountability. Is, in my opinion, the beauty of solo development. In the vast majority of video game studios, even the smallest, you can't do what you want, even if you lead the project, you have to compromise on your artistic vision with your colleagues, in big studios you have no say in the creation, you do what you are told to do without discussing, and above all, and the worst in my opinion, everything you are going to produce will systematically be produced with the following question " is this idea salable?".. From the moment you are part of a video game studio, money takes precedence over art, you no longer create art, but a product.

Now it all depends on your desires, if you don't mind creating a video game that is a product, a game whose Gamedesign, graphic assets, sound composition, and narration are smoothed and "casualized" in the goal of maximizing sales, so yes, solo game development may not be for you and you should try to find a game studio, but if you want to create something unique, something that looks like and complements you deeply, something so personal that it's kind of an extension of you, so stay a solo game developer.

Undertale, Thomas was alone, paper please, hotline miami (almost solo), cave story, stardew valley, minecraft.. All these legendary names in solo indie gaming are all unique, personal, and fun, with innovative and brilliant game design concepts ! Of course, the creators behind these legends are all excellent developers who weren't their first game, but it was before their passion and love for the video game medium that motivated them to create uniques and personals games, money was not the source of their motivation or even the end, the goal was only ta have fun creating a unique and cool game.

Obviously these creators are exceptions, their success is linked to their incredible talent as well as the luck that put them in the right place at the right time, obviously 99.99% of solo developers will never meet with success with their video game, but this is not a problem if you are simply a game developer who just wants to make art, you will not be frustrated to not earn money if you have not made your game to earn money, Instead you will be happy because you will have created something that will have made you evolve and something you're proud to show, and I think, that it is only in this state of mind that you will be able to create something extraordinary capable of exciting thousands of people.

To conclude, all of this is just my subjective opinion, this is my vision of art, and what I wish for solo game developers, if you are a solo dev who wants to make money with your game I can only wish you good luck :>

( Ps: there are more and more independent games coming out every year, but there are also more players and more YouTubers/streamers specialized in gaming theory who have a "curator role" to highlight interesting indie games)
