I don't think i have ever built a CE center.Even for the morale boost. I wouldn't have even noticed it gone. At most I've had one or two AI spies that i couldnt get rid of imediately. I understand that its possible to have a few other races attack you at the same time; but even then, how many spies are we talking about? I would go so far as to call it a game ender or that the race can't be played.
For those races you'd have to change up your strategy and have a larger pool of spies. I know, they cost a lot. BUt thats just how those races are. Just like you had to dramatically change your style to succeed as the Yor. Now if they couldn't build spies at all, that would be a broken race.
Besides there is apparently going to be a major change to sping in 2.0, i think.
Well, its the old DA espionage-hate argument, which I dont really want to dredge up again here...its been well documented on the boards for the last year and a half, is a common complaint, and Im sure the devs are aware of it by now. Sometimes its an issue, sometimes it isnt.
It just has to do with how large a map you're playing against, how many opponents, and how early you manage to pull ahead in the game. I think it probably works ok for smaller, faster games, but it doesnt scale well. On medium and larger maps you simply can't keep up once you hit the top 2 in Civs, and everyone is carpet bombing you with spies, you have too many worlds protect, and spies only get more and more expensive with the larger economy, so if you bankrupt yourself, you *might* be able to manage a game of "whack a mole", barely keeping up, but nothing more. Meanwhile your world's best tiles are perma gimped from constant spy attack, and the two or three turns behind where you are when you can remove them. The map is large enough and the opposing civs have enough worlds, they cant be quickly dispatched without a lengthy coordinated effort.
And to add insult to injury, this is all largely money that you're forced to waste, because spies have such little real value in the game other than as a fun tax/moeny sink. Oh, not that using them doesnt have benefitrs that are generally positive...but theres nothing even remotely as beneficial as using that money for other purposes, like building another fleet, rush buying important buildings, or being able to run your tech slider higher, etc. This is on top of the fact that the economy is generally trickier to manage in TA (which is a good thing).
Sometimes you arent targeted heavily because you dont pull ahead until later in the game, when you're basically sweeping the map, and half the civs are already dead, so its not a problem. But it can happen early in the game if youre in a situation where you're forced to strike out early militarily or with influence and population numbers..or even playing a race thats *designed* to do so. Even building a few gimpy defenders to deter from invasion can do it.
Without CE, the only way to protect against that kind of situation is to metagame, and basically puposefully try to to limit your civ's influence and rating, against the nature of the game, all in order to avoid being targeted.
For reference, I play medium or larger maps, on Crippling or Maso difficulty depending on the build. This is my sweet spot, as I find the harder difficulties than that challenging, but they stop being fun, as its more about using exploits and metagaiming to survive the impossible AI tech bonus... so I dont really think Im playing on "too easy" a difficulty. I'm not a master player, but I am an experienced one, and know how to build my civ to max economy and population growth, so Im actually pulling ahead much earlier than I used to in games, and am being targeted earlier. IN TA, regardless of race, by midgame Im usually making from 300 bc to 1000 bc per turn...every cent of which I could pump into spies and still not be able to pull ahead or keep up if its 8 against 1 espionage.
So its not so much that that the races are technically unplayable, as the DA espionage system doesnt scale well, is too punitive for too little benefit, can be horribly un-fun...and CE is the only way to shut it down and avoid that kind of situation. As long as espionage is in this state, untiol 2.0 which will hopefully fix it, the ability to counter it really needs to be availiable for every race.
