There will probably be a drawback though:

So I added sprinting, just to try it out. Double tap forward to start running, like the fast jump move thing from Unreal, but it only works forwards, like sprinting in most modern FPS games. It felt slow and weird until I added a FOV change as well, but now it's fun and addictive. I feel like there needs to be a drawback to doing it, though, or you'll feel like you're wasting time when you're not sprinting.
