It feels like the announced changes are a result of 343 trying to hard to make Halo their own. Rather than make intelligent and rational changes, 343 is completely changing what made Halo, Halo.
Randoms will argue that we need to innovate the franchise but this can be done in other ways that turning the game into Call of Duty. Engines can be modified, technology and graphics augmented or secondary systems that surround the game and be implemented to improve the overall product outside of the core mechanics of the game.
These randoms argue that if we don’t change Halo then it will just be the same game year after year. The overused cliche argues, “If it ain’t broke don’t fix it”. Change the investment system, play around with the menus and fix the algorithms to make a more efficient game. However, completely changing core mechanics that made the game what it is today, those are mistakes.
