Why climb a mountain, or fly to the moon? Because it's there. It's a great challenge that hasn't yet run out of new places it'll run. I can say that the first time I ever ran DOOM, I was blown away because I had no idea my computer could even do that. The game is forgiving of poor specs, even though it is in 3D space. So it runs on just about anything. Got a new microcontroller? Sweet, does it run DOOM? The answer is either a) of course, or b) not yet. What a great challenge that sometimes really surprises.
