The first thing is I'm new to this forum, so I'm sorry if this post breaks some rules, duplicates, inappropriate or whatever.

I accidentally found a really interesting course about Game Design.
https://gamedesignconcepts.wordpress.com/2009/03/31/what-is-game-design-concepts/

If anyone cares, we will make a group and take this course together. Of course, you can take it on your own, but I think it's better that we have mates to discuss and share our works.

You can contact me via my email: [deleted by moderator - you can contact via this website's PM system]
or just reply this post.
Thanks.

Hey dude thanks for the link.
