I cited you as a first-party source, unless you're lying I believe I'm correct.
The issues as I see them
1. You routinely fail to grasp the concept of what engines do different things, and yet you demand information be spoonfed so that you can teach others, instead of simply learning about the (not impossibly hard) tools people have explained to you over and over again.
2. You have no passion for games. This is self explanatory. You don't care about gaming. That's fine, unless you want to do something like teach game-related classes.
3. Have no knowledge of game development, yet constantly ask for tools that allow well-polished games to be made with no programming...
4. Don't seem to understand games yourself. Which is fine, why would you, unless you had a passion for games/game design.
Seriously, how can anyone suggest any course of action besides telling you to step down without a straight face? You'll be miserable spending years of your life learning/teaching something you have no passion for, your students will be miserable dealing with a teacher that doesn't share their passion (This is why I dropped out of highschool FYI), and your school district will suffer because people won't be interested in your classes.
You constantly bring up art in your posts. As in, you talk about art more than game dev.
So, go do art. Make sense?
Believe me when I say I'm not trying to be mean, I'm trying to let you understand that if you're not passionate about games, then your students will know WAY more about game design than you.
To put it into perspective, when I was your students age I had several thousand hours of experience working on hobby games/mods that were downloaded tens of thousands of times. What exactly would you offer to a passionate student in a similar situation? Would you care about his achievement? Of course not, because you're not passionate about games.
You're asking about creating a lesson plan about a field you know almost nothing about, nor care about, and have demonstrated such poor grasp of the concepts required to teach the subject that no one's even bothering to submit constructive criticism on your post.
Your lesson plan boils down to
1. Play board games in class (Another topic you admitted you have no passion for nor care about).
2. Draw characters then create those character in 3d (because 3d characters are so easy to create)
That's basically a full lesson plan for college-level courses, but then you keep going.
3. Teach game history/types of games, (when you clearly don't know anything about different genres of games, nor do you care about them.) also something about how science and art mix... Which means nothing.
4. Making a game (Because you might not care about games, but it's in the course name so I guess this game-making stuff will have to get in the way of your art class at least a bit!)
Why do you insist on doing this if it's clearly a field you don't care about/have no knowlege of?
What makes you more qualified to teach it compared to the students you're teaching?
Again:
I don't care for video games in general
So why are you trying to teach about game design instead of art, which is something you actually do seem to care about?
