I gave my reasoning too!
Ultimately, everything new/different ODST did well was either pretty minimal in the grand scheme of things or was not executed very well. I definitely had much bigger hopes for a concept players have been begging for for years only to be treated to lifeless characters and probably one of the most boring open worlds ever, so bad it even begins cutting into the atmosphere when you become cognizant that wherever you are now looks exactly like the place you just left.
The idea they sold was VERY different than the game we got, that's why it's more disappointing to me than Halo 4, where you could see pretty much every flaw coming outside of the mid-campaign info dump and terminals still being pieces of shit that don't belong in these games.
The campaign was alright IMO. The level design was very good and reminiscent of Halo 1 and the story was much more developed than any other Halo. It's just the Promethean design was absolutely horrendous and one dimensional which made gameplay suffer at large.
The multiplayer was more offensive than Reach not just because it introduced more unpredictable elements into gameplay but it also began to steer away from the core of the design where now you had to unlock guns. Big fucking no-no.
I have faith that 343 can make a good game (ultimately, Halo 4 is a pretty impressive achievement taking the reigns of such a franchise, who else has ever had that much pressure?), but until they change the pillars they decided were what makes a good Halo, you might not ever see the multiplayer especially back anywhere close to as tight as it was in Halo 3.
Well that's a surprise. Could even see a JP console release in the next 6 months and maybe a domestic release before 2018.
