Im glad someone else noticed this. Slipspace is nothing but a heavily reworked Halo 5 engine (looks NOTHING like their in engine demo 2 years ago). Normally that wouldn't be a bad thing if they could AT LEAST hit the visual fidelity mark of Halo 5 in an open world setting. Yet somehow, it barely looks better than Halo 3. Put Arbi from Halo 5 next to Escharum (?) from Infinite, its a significant downgrade for "the most powerful console".
I can't blame 343 as much as Phil Spencer for shackling this monster to that 8 year old VCR relic of an Xbox.
Remember, they're saying this is the ONLY Halo game we're going to get for 10 years. Any hope anyone has for a better, more "next-gen", super-ambitious Halo (ie a fully explorable ring world) is already DOA. Whatever they have now, that's it, for 10 years as they bolt on expansions and "upgrades" (ironically like a Lego set).
Its not good for Xbox, Halo fans or 343i. This game should have put Halo (and Xbox) back on the map, instead its going to fuel bad press about how lousy Series X consoles end up selling. Its a shame this is where Phil has led the Xbox brand.
