Indie game developers are small teams or individuals who create video games independently, without the backing of large publishers. They often focus on unique ideas and innovative gameplay, allowing them to explore creative concepts that might not fit mainstream trends. This independence gives them the freedom to experiment and take risks, resulting in diverse gaming experiences. Many indie developers rely on platforms like Steam or itch.io to distribute their games, making it easier for them to reach players. Popular titles like Celeste and Hollow Knight showcase the talent and creativity found in the indie scene, proving that great games can come from anywhere.
