I think the players will make or break Eureka. If there is sufficient interest for this sort of higher-risk higher-effort sort of content, then the zone will remain active and the population stable, which should keep things moving along.
If, on the other hand the player base abandons this as too “unfun”, or “too much effort” or “too hard”, then the devs will have the proof they need that this sort of design philosophy that worked in 2002 no longer does in 2018, and people can finally stop trying to bring it back.
Either way, it should prove interesting.
