And I was also annoyed that the guy didn't pick up on the problem of the expiring Wonders. Of all the Wonders in the game, both the Oracle and the Temple of Artemis stand out as being particularly frustrating in this regard.
Let's have a look at the expiring Wonders:
Colossus - lasts all the way to Flight, basically the Modern Age, by which point its passing is annoying but barely noticeable. For games where you expect to be pretty much finished by that point (most of them) it's no great loss. I like getting the Colossus, it's like a talisman of Tech-gain providing one extra city's worth of Gold each turn. Very cheap and sometimes is the only building option aside from Wealth, making it a natural for a low food but high production coastal city that's waiting for Map Making. Not a great loss if you miss it though. Great for using in concert with Copernicus, Newton.
The Oracle - Quite cheap but doesn't last very long and requires other buildings to be effective (completely useless if you've got no Temples other than it's Culture and later minor Gold), mainly works in consort with The Temple of Artemis, an extremely expensive Wonder. Having one without the other feels a bit lacklustre. Causes revolts micromanagement when it expires (or in preparation of).
The Temple Of Artemis - See Oracle. Doesn't last very long, possibly only 2 Techs in some games. Mainly a good Culture tool early on. But wow, very expensive in comparison to the Pyramids which offers something permanent. Causes revolts micromanagement when it expires (or in preparation of).
The Great Library - doesn't last very long but is a great boon if you're behind in Techs for whatever reason or if you want to sit back and do other things while the other civs spend money on Tech, such as buy buildings or pump the happy slider for growth. Very expensive. Could save you having to trade Techs you didn't bother with. Kind-of Unique with some interesting uses and is too OP to be a permanent benefit anyway.
The Great Lighthouse - Quite cheap and one really for the Archipelagos, relatively useless on Pangeas (but if it was free...) but a great defender and attacker for the open seas. It's extremely possible to have also built it's permanent replacement by the time it expires (Magellan's) making it's passing completely unnoticeable.
The Statue of Zeus - Military Units, if you have Ivory then you might as well, it's unlikely (possible though) anyone else will even be competing for it. Expires a bit too late even, well after Chivalry and since you can't upgrade them they start to get a bit annoying and only good for Production transfer or the odd game where you can't get Horses/Iron for whatever reason. Great for the BC years and a little further though.
The Great Wall - makes no sense at all really. Mostly only good for a pre-build for the sudden influx of great Medieval Wonders. I'm sure someone's found a use for it at some point, maybe in league with Feudalism, but it's pretty lame by all accounts. If it was empire-wide with permanency then maybe good for those far-out conquering places that starve down in size as you trample them, but since it expires before Cavalry it has a very short window of use in that regard.
The Hanging Gardens - Quite cheap, provides content people, lasts all the way to the Industrial Age, one of the many free half-luxury Wonders you can accumulate. Can be replaced before it expires with JS Bach's. Causes revolts micromanagement when it expires (or in preparation of) but has given you more time to accumulate other sources of happiness than Oracle or ToA in this regard.
Knight's Templar - See Statue of Zeus, only doesn't require any resources and is foot soldiers rather than Horses.
So when I look at that bunch with either good production or a lucky SGL or two or, generally, most strategies it tends to go like this:
Colossus, yes, nothing else to build and pretty positive, Great Lighthouse, mmm, great, wouldn't say no, Zeus and Knights, yum yum, more the merrier, Hanging Gardens, nothing wrong with that, might just quickly zip that out, Great Wall and Great Library tend to be pre-build storage for me, leaving just Oracle and The Temple of Artemis which I have in this awkward category of good, but not good enough, kind of really frustrating.
If both the Artemis and Oracle had been permanent, or at least lasting until the Industrial Age, then you've got a really good path to follow, bouncing from Oracle to ToA to the Sistene Chapel, but having them both expire a couple of Techs after Monotheism, before you can even build Cathedrals in most of your cities if you're pushing for Education is just so clumsy gameplay-wise, all that additional micromanagement of cancelled contentment while waiting for new contentment combined with the fact that they both cost so much together. With all the other Wonders, if there's a replacement Wonder then you have a good amount of time to build it, but with these two it's right on point of the change, really awkward.
It's without doubt that in the BC era having the Oracle and ToA feels great if you have the tech lead and production or lucky SGLs to get them, but it's so anticlimactic and so much of a hassle when they end and don't really work in unison with any future Wonders that I often refuse them just on principle of them being too annoying, too much hassle. If they kept working with the SC, then, wow, I'd be starting with a lot more Religious civs, even in Science race games.
