On a positive note, some of the views of the scenery stretched out for miles at 4k looks jaw dropping.
But…despite the open world approach it just doesn't seem to be doing anything new. We're still in the same evironment and fighting the same three or four enemy types we were twenty years ago, and that's the very last thing I wanted from the series. The limited biome and open world structure also means we're probably not going to get many set pieces and I've yet to see an epic vehicle battle.
For all the hate Halo 5 got for its too short campaign and terrible story, it at least felt like it was trying something different. New movement options, new characters, new environments, new enemies and vehicles. That's what I wanted to play more of just with a less shit story. Not "The Silent Cartographer the game". I've played The Silent Cartographer for decades and well over 100 times. I'm bored of it.
