Are you going to start playing Reach again?
Personally, I cannot wait to play Halo Reach on my Xbox One. Although I do like Halo 5 so far, I still think that Halo Reach retains the position of my favorite Halo game so far. Unfortunately, after 6 years, the population has declined due to the release of later Halo games and the release of the Xbox One, causing some players to abandon the Xbox 360 in favor for a more modern console. With backwards compatibility, however, I'm hoping that a significant amount of people will return to the game and start playing it again, not only as a quick method to appeal to nostalgia but also to fully reintroduce it as a game they will play often.
