5. We Can Explore Gallifrey
We've only explored Gallifrey during the runs of the first 8 Doctors, and after the relaunch we've only seen very few shots of Gallifrey, either during flashbacks or during brief scenes in specials like Day of the Doctor and The End of Time. Even then it was just a view from far away, followed by a single room with a spitting Timothy Dalton. The most we've seen was during Day of the Doctor and Last Day, in which we see the magnificent city of Arcadia. I've got to admit, even as a completely destroyed city it was pretty impressive. We can only imagine how the rest of Gallifrey could look like during its glory days. With the current budget and the continuing improvement of special effects as time goes by, we could finally see the Doctor and Clara wandering through Gallifrey's forests, or exploring their great cities. It would be great to see the Doctor having an adventure in his home planet.
