This is not about the OG Xbox Halo games but the Xbox 360 ones, and even then Halo 2A on MCC is still superior to Halo 2 on OG Xbox. The only Halo games where MCC is inferior in some ways is Halo CE.
But this thread is about the Xbox 360 Halo games which are superior in almost every way in Halo MCC.
I mean, I understand, but there is zero sense in axing Xbox Live on X360. They just recently made Cloud saves free on X360 and hopefully the scalability of the Xbox Live is enough for X360 to live on. Come on MS don't be pussy.
I hope, At least, that in the not-so-distant future some 3rd party provider buys a catalogue of licenses to MP accessibility of various games, setups up a MP hosting service, and provides a way to re-experience various MPs of the past. Sorta like GameSpy did back in the day.
