Destiny and Marathon are vastly different formulas. Destiny required frequent, resource heavy updates to keep players engaged. Marathon is a significantly deeper sandbox that will keep players engaged much better between updates. People have to start wondering why Chess has lasted so long with 0 DLC.
I think the astroturfing campaign is working, it's generating FOMO... Can they deliver long term?... At this point the actual "vibes" for marathon are incredibly obfuscated.
