The War Games marks the end of black and white 1960s Doctor Who and the end of Patrick Troughton's superb reign as The Second Doctor. These aren't the only seismic changes which can be found within these mammoth 10 episodes. It features the introduction of the term 'Time Lord', The Doctor's home planet (not yet named) and an explanation as to why he left. It was a brave and brilliant move to confirm that The Doctor does not necessarily see eye to eye with the rest of his race, disapproving with their 'hands off' approach to the universe. This story also features the first re-occurrence of the sonic screwdriver since its introduction in Fury from the Deep. Terrance Dicks and Malcolm Hulke are working hard to consolidate and extrapolate on the show's lore - which we should be grateful for. Not only does this story establish so much of what becomes vital to Doctor Who in the future, but it also has one of the most ingenious plots at the centre of it that the show has ever seen.

The Doctor, Zoe and Jamie uncover a plot to conquer the universe. Brainwashed soldiers are being taken out of their time and tricked into believing that they are fighting their own wars in simulated environments. The aim is to create an unbeatable army which can be used for plotter's own purposes. Luckily, there are rebels who have managed to overcome these brainwashing efforts. They group together with The Doctor and his companions to overthrow this corrupt prison.

The War Lord, the malevolent Time Lord in this story acts as yet another 'proto-Master' villain. This character is just one of many enemies The Doctor faces in The War Games. It needs these extra elements due to its outrageous length. The quality of episodes 8-10 is difficult to rival, which is what makes it my third favourite Second Doctor story. However, I believe it would be fair to say that the first seven episodes could easily be cut down to four. Once you are introduced to the strong concept behind this story, it takes a little too long for the mystery to unfold.

As the adventure draws to a close, it is clear that it is the most epic tale The Doctor has ever had to face, so dangerous in fact that he has to bite the bullet and inform the authorities on his home planet. He knows that this move will consign him to a trial himself, as he regularly breaks the conventions of his people. The consequences of handing himself in were so much greater then he ever could have guessed.

The Doctor's defence of his actions is powerful, he demands that the Time Lords see snippets of the enemies he has defeated (including the Quarks!) He makes a spirited justification of regularly interfering with events to put a stop to evil. The Time Lords accept that this is a difficult moral quandary for them, but after careful consideration simply believe it is unforgivable for him to interfere to the extent that he does.

The War Lord and his assistants are dematerialised as punishment, which marks The Doctor's victory. However, he has to lose Zoe and Jamie, who's memories of almost all of their time with The Doctor are tragically removed as punishment. This, especially for the longest running companion Jamie is drastic, he finds himself back in The Highlands where he began. The Doctor's own punishment is a banishment to Earth and a loss of his Space and Time travel capabilities. Again, we can see the writers shaping the form of the show to come - it could barely be more exciting. The Doctor is defiant as he is forced into a regeneration, it is a wonderful closing chapter to a version of the character which has undoubtedly changed the essential nature of the show forever.

I cannot wait to begin the show's third leg and am delighted to see Doctor Who more fleshed out than ever. Patrick Troughton has out shined William Hartnell's excellent efforts and has finished his time on a definite high. This is a story I will always hold dear - top stuff!
