With everyone already understanding that Marathon is probably dead before arrival why can't bungie change it up? Destiny already has Marathon and other games in their universe. Who is to say Marathon can't be in the same realm? Frontiers should have us going out into the universe and visiting other worlds and find the Marathon U. Bungie could use Eris piloting or finding info on the dreadnought about other worlds. Xur and Starhorse already have dares helping fuel the crossover. Drifter takes us out to other planets and we encounter the other Universe. Take the pvp pve maps from Marathon and use them. Warminds and even Maya now in the vex network interacting with the AI in Marathon. Have their universe be before the destiny verse and make it canon. Thoughts?
