Yeah N4G is a good resource. I think there are other sites like it though.Sometimes here, but I also use a site called N4g that aggregates all the best gaming news stories in one place. It also allows you to upload articles to their database, and sometimes helps you get more publicity.
Mostly through YouTube and Facebook, really. I also take a look at gaming forums such as this one and more specific ones such as Reddit (since they have subreddits for almost every game out there).
Yeah youtube is great. I usually find a lot of my news just from YouTube alone. I will also find news from Facebook and Twitter as well. Basically any social media will do.Youtube. There are many games channels with news and updates of all games c: Better i didn't found!
