Games programming is rather difficult, yes. Especially 3D games. But also, it's easier than ever. I would have loved to make 3D games as a kid, but my lack of art skills made it impossible. Now with the Unity Asset Store, suddenly a simple programmer like myself can make some really good-looking 3D stuff.

I've been working on a Metroid Prime clone in my spare time just for fun in Unity. And yes, what the author says is true - it's really freaking hard to get all the details right. Even something like weapon bobbing when you move takes some thought. But it's really rewarding and fun, and I am basically making my dream game. I don't expect to ever release anything, but I'm enjoying the ride.

Also, anybody ever write DarkBASIC as a kid? This was the first programming language I ever learned, because I wanted to make games. It was a great intro to programming.
