I haven’t even watched this yet, but I’m going to recommend it just because I know it’s going to be so, so good:

This is a playlist in which James Chen takes you through the basics of the theory behind fighting games. If you think you want to play Street Fighter V (or any fighting game for that matter) you should watch this. If you have ever watched a fighting game tournament and wondered what was going on a lot of the time, you should watch this. If you have a passing interest in game design and want to learn what makes these games tick, you should watch this.

And hey, look—a WordPress-based site. :)
