I'm having an excellent time recreating Breakout! in Unity to learn a new Finite State Machine system and eventually build some original game prototypes. It really is magic when you have set up your logic, your controls, and the experience emerges.
So basically I have successfully recreated a 30 year old video game in Unity. A huge improvement over my last effort (circa 1984) where I wrote a Basic program that moved the cursor around on the screen with the joystick on an Atari 400. :)
