Freelancer is not a space simulator. It's essentially an FPS in space. The current scale of things is just fine. All you need is some suspension of belief and it's real space.
If you want a simulator Try the X-series. They have planets that take an entire day to fly around at 1300+MPS.
But holy hell does it get boring. If you don't have an empire to manage en-route getting anywhere is ridiculously tedious.
