So I've got it now, Live gamertag is "Da Crum". Multiplayer is hit or miss. I'm doing well, but if my team sucks, then I'll start to suck and then I have to take a break before I become good again. It's weird.
As for canon discussion, since Forerunners(and humans) were the only Tier 1 race(labeled "World Builders"), and as obvious in Halo canon, Forerunners built massive worlds such as Onyx and Requiem, I can only wonder where they got the materials for these, amongst other structures such as the Halo rings. Harvested material from lifeless planets?
Escape will make me God.
