From an external survey it would seem Microsoft is pondering outside-the-box strategies for the Halo name, like more 'family friendly' adventures.
Participants of the research survey were asked to mark next to each idea on what scale would they be interested in purchasing these Halo games.
The scale ranges from "definitely would purchase" to a "definitely would not" on game ideas like a racing title in the Halo universe. Even a LEGO Halo game gets a mention and frankly would no doubt be the most successful of the bunch - you just know it.
One such notion was a Halo shooter where you don't play as Master Chief - blasphemy!
