I played the shit out of Halo 2, 3, Wars, ODST, and Reach back in the day, and the franchise was the reason that I got an Xbox 360 in the first place.
When Halo 4 came out though, I distinctly remember not being as enthralled with it, and while I couldn’t quite put my finger on why, I eventually came to realize the reasons for it over time (which have been covered ad nauseam by people like Chris Ray Gun).
I didn’t even bother with 5 or Wars 2, since i went with the PS4 over the Xbox One due to the former having what I saw as more appealing games. From what I’ve heard, that’s probably for the better (at least with 5, I don’t know enough about Wars 2 to say whether that’s definitely the case).
Watching the gameplay reveal for Infinite, I see a game with potential but also one that’s going to need a lot of polish in order to live up to it (particularly with regards to its visual presentation). Nevertheless, I would love nothing more than for the game to be good enough to justify the purchase of an Xbox Series X and for me to enjoy a Halo game again as much as I did when I was heavily invested in the series.
