Perhaps the hyperdrive could have a limited number of 'charges' or a limited range. Going too far or using it too much results in structural damage like when you go through black holes. I agree it does make exploration and travel easy, but sometimes it saves the day: numerous are the campaigns I've had where I've been unable to get anywhere thanks to large amounts of nebula and no suitable drives, and then suddenly, a year before I'm due back home and I find the hyperdrive. It unbalances play as much as the Particle Vortex Cannon, but saying that I use both whenever I find them!
