I've just completed a game and didn't have any problems when i went over 1 million (except that it displayed as exactly 1000,000) so maybe they've quietly changed the number type?
I hadn't previously remotely appreciated the power of the the port of call but was intrigued by the initial post and tried the Yor at Genius on a huge ,map with nine random opponents. Although I only managed to colonise three more planets, one was a precursor research world and using it for research and Iconia for production generated more than enough of both and about +450 gold a turn with just those four ports of call.
I spent the rest of the game, bashing and trying to maximise wealth but I am v impressed by +250K at move 100 ish. I guess that was with a tech tree that has the tourism expansion since even at 100% tax with robots I only got to +73K per turn about move 200ish before dropping down when i changed to the Singularity government type
My only problem in the latter stages was generating enough resources given the way that the market works. I wanted to keep Durantium and Promethion at 100 and only got 2 or 3 a turn that way plus 5 ish from start bases; and whatever I could buy from the remaining civs who all hated me (apart from the Terran Resistance) and so were charging prohibitive rates for resources
Anyway, While it was fun once, I agree that the new economic model is broken since tourism + ports of call are just too powerful; and . I gather (we were pragmatic robots so I didn't get to test this) that Missionary centres accentuate this even more.
Any suggestions from anybody on ways to remedy this without the sort of dramatic lurch that Stardock seem to implement every time they change direction? Perhaps ports of call could operate on a sliding scale (downwards). After all, there are presumably only a finite number of tourists to go round.
Incidentally, the battle viewer still isn't working - sticks at the opening scene. A little irritating when you have a serious engagement. Any ideas short of reinstallation on how to remedy this? (As far as I know, my graphics drivers haven't changed recently.)
