Good vs Evil: Exploring Moral Choice in Video Games and its Effectiveness in Storytelling
Many games use various moral choice mechanics to allow players to role play and influence the story and outcomes of a game. Unfortunately in most games this usually boils down to the story having a "good" or "bad" ending as the player makes various red or blue choices (Mass Effect, Infamous, etc) and there is rarely any point in trying to do a mix of each as these games don't have option for playing the middle. (in some cases gameplay abilities and content will be behind 'you must be this good/evil to ride this ride' sorts of walls.)
My thoughts for an article would be in exploring ways that moral choice has been used effectively and innovatively as an aid to storytelling and not become secondary to gameplay mechanics. Games like Iji and Undertale (non obvious moral choice and consequences), Bioshock 2(which has a great example of a developed middlepath), Telltales Walking Dead (no right answer choices).
If you have any other ideas for games you think handle choice well leave them in the notes.
