Doctor Who: 10 Things The 2021 Video Game NEEDS To Be Great
10. Doctor/Companion Co-Op
The relationship between the Doctor and his companions is at the heart of Doctor Who. They aren't just total strangers sharing a box together: the Doctor's friends actively make him a happier, better person (just look how unstable the companion-less Tenth Doctor became towards the end of his run), and in return, the Doctor enriches their lives by showing them the wonders of the universe.
And because the companions are so important, making them dumb AI robots whose only purpose is to boost you over ledges would do these characters a disservice, so it would be much better if the game allowed for co-op, with one player as the Doctor, and another as the companion (assuming that companions are in the game).
Sure, some players prefer to go it solo no matter what, so the companion will have to be computer-controlled some of the time. But at least having the option to bring in a second player can't really hurt, and in fact, it would only improve the experience.
A playable (or AI) companion also solves an issue that a lot of Doctor Who games run into: the Doctor doesn't kill, and it's very hard to design a gameplay loop built around pacifism. But characters like Mickey Smith or Captain Jack? They have no issues when it comes to using guns, so they could handle all the violent stuff.
