Wow this is such a cool idea, I dreamt about making my own video game magazines since I was a teenager. I don’t have any experience in making one though, and I am not a native English speaker so writing may not be great, but I guess we have awesome editors for help with that 
I am from China so maybe I can write some video game history in China that is not well known in the English speaking world. I had fun sharing this story a while ago: Weekly gaming history exercise #1 - #17 by Kirais
I am recently very into retro handhelds too, so i can write an article about that. Let me fill the form to pitch ideas!
