Is it too expensive to use a particle system for a dynamic background?

Questions & Answers

I'm just creating your standard (2D) space game, where the ship is in the middle of the screen and it just rotates to shoot at oncoming enemies. I'd like to have a moving background (stars), and from other posts it seems like I'd need use an animated texture (which is fine -- I can look into doing that).

But the idea occurred to me to use a particle system that shoots starts down the screen. Just wondering if that's a viable solution?

As Mike said, it all depends on what you are doing, ie, how complex your particle system is. But, having simple particles to simulate motion in space has been a common technique in video games since the early 80's, so you should be able to pull it off :)

If you don't go overboard it should be fine
