Question What's Difference between Main Camera and normal Camera?

Hello,
I'm new to unity and I'm currently programming my first video game, a 2d-plattformer. I accidentally deleted my "Main camera" and I have created a normal "Camera" instead. I didn't encounter any problems, but I'm still wondering if there's a difference between the "Main camera" and the normal "Camera" and if there are any problems if I continue using the normal camera (I'm planning to play around with "Cinemachine").
Thanks in advance

 

There shouldn't be any issues with the camera, but if you're feeling paranoid you can always just change the tag of the GameObject with your camera to "Main Camera". Other than that there is no difference between them. I wish you good luck with Cinemachine! (It can be a bit tricky to set up but don't let it get the best of you)

 

Thank you very much for your answer
