Having drifted away from consoles for a few years after Halo 3, and only in the last year playing through 4 and 5, which I had to force myself to finish....I wasn't expecting much.
Master Chief is a dull as dishwater hero and the lore with Cortana is an absolute yawnfest, always has been....that's why 4 and 5 were so weak....they leaned in too much on the weakest parts of the game, and didn't improve the core.
Infinite for me is exactly what Halo should be in 2021...it's taken the essence of the game, levels like The Silent Cartographer from CE, and used modern hardware to make en experience that focuses on the best parts of Halo.
Great gunplay, meaty vehicles, smart AI, loads of polish, awesome audio. I've really enjoyed it so far. I'm kinda hoping it doesn't go on too long, but I'm happy plugging through the map at the mo.
