That's how Codemasters got started.
I often see console game effects and go replicate them, but I think that's where most of us suss out game techniques. Like the fire in Unreal Championship, it looks cool and most people would be impressed, but it's just a plain floating up the screen, once you figure that out replicating it is straightforward.
You might never use these little tricks in a game, it's just good to know what and how you can do this stuff, it kinda broadens your horizons in terms of the sorts of games you end up making.
