Actually it is, but moreover, it is full of cool tips, forums, news letters...etc. a full community for game developers.
They also have a range of tools that even beginners can use to start building games, some don't even require programming skills.
the best place to start on this website is to start by watching the "About The Game Creators" video on the landing page.
I forget to tell you, this website allows you to list your games (that you developed) on their online store. Another cool thing that you can make use of on this site.
Watching the video kind of motivated me to start building games.
After all, it's fun, and it's a multi-billion dollar industry.
