To add a story and content to the subject of the endeavor master set:
The redone endeavor master set (and the Explorer packs) are the best legacy (besides 1to1 interaction) CIG's HartsWoe left us.
I melted mine and have a few more in buyback but will eventually buy mine back when endeavor becomes flyable.
If you must own endeavor modules with LTI, the newer master packs are the best option (without VAT).
HartsWoe noticed my comment that the original master pack was missing an additional biodome so that the master pack could be configured in any and all sold configurations of the endeavor.
He commented and took note, then a few weeks later (or months, I am foggy on that) the new master pack was released with that extra biodome.
Anything HartsWoe put his hands in immediately turned to gold. Like the explorer packs and other concierge offerings.
Not to mention, he was a champion of, if you ask for it and reasonable then yes. Before Concierge was reluctant or stingy with selling unavailable CCUs or pledges, nowadays (I think contributed to HartsWoe's involvement) concierge allows CCUs like a kid in a candy store, kind of balancing out that artificial scarcity issue. Well, any opportunity for me to show appreciation for what HartsWoe did for our community I kinda take the initiative to share so it's not forgotten. Since he left, we have not had another HartsWoe type take up his mantle.
So, if you have an opportunity to buy the non-vat Endeavor master set (the newer ones, not the original) I would suggest getting it.
