I'm currently trying a game with the splendidly evil Xraki and now winning easily. But I have been waiting to build the Douglas Adams tribute wonder the Restaurant of Eternity for - well an eternity it feels like.
The wonder requires 3 Aurorus Arboretum and 3 Artocarpus Viriles. I have plenty of Aurorus and can in any case send a Xylology expedition to gather some if necessary or trade for it with other factions. But the map seems to be completely devoid of Artocarpus (nobody has ever had any to trade so maybe it's on one of the minor faction's worlds if at all) and I don't think there's an expedition for it is which you tech up to?
In any case the market price is 850 so I can buy at 850 and 1000 but still be one short. It's been stuck on 850 for the last, I didn't look when I started, but at least 30 plus turns.
So I've got two questions.
Firstly how long does it normally take before the price of an unbought item near the top level drops?
Secondly is it optimal to wait or to buy once at 850 to put it at 1000 and wait for that to drop or buy twice at 850 and 1000 and wait till it becomes available again at 1000?
Many thanks in advance to anybody who understands the mechanism.
