Speaking as a someone who comes from a family of journalists...
No, you don't need a degree to do that job.
Especially if we are talking about something specialized, like video-game journalism, what you need is a good understanding of the subject matter.
My mum has a degree and a 30+ years of experience, but she knows nothing about video-games.
Would you trust her opinion on games more than Sterling, for example?
She used to play Minesweeper a lot.
She could write a good-looking article that reads well, and bullshit to probably fool a layreader (she used to work for a daily newspaper where she'd have to write articles on subject matters she knew nothing about, and most importantly, do it quickly.) and given time, she could write a good article from a point of view of a layperson.
So what?
Now, if someone had a degree on game design or something, and a background in game development, then you'd have some idea they know about that side of things and can give you a different perspective than most people.

I figured someone calling themself a journalist would need a journalism degree. There is a Patricia Hernandez who has a degree, but she'd a Ph.D in biology and something tells me Ms. "Should killing female gamers in online games be considered rape?" didn't study biology.
What were the mistakes on that article (that I haven't read) that were purely about biology? Did she misspell 'vagina' or something?
And your video won't be particularly well researched if you go about it by asking random people on the net. Ask those people directly.
Here's a quick journalism tip:
Get actual sources. Someone telling you on a forum that Jim Sterling is actually a rocket scientist working for the Soviets is not particularly reliable information.
