Matthew, you're ignoring the fact that generally with Liberty and the smaller cities you end up with, and longer build times, you can't afford to build as many buildings.
Two things. Well, three.
1. You don't need to build a lot of buildings, or at least when you normally would when going tall. You don't need aqueducts, nor granaries/water mills right away. A lot of buildings, like stables, windmills, and such are rarely worth it in most cities.
2. To grow taller you need a larger food surplus, which means a portion of your cities is solely dedicated to working food tiles. With wider play, you can stretch citizens further and be working just as many hammer tiles in many cases. A food surplus of about 4 (the amount of one granary and the city tile) is typically enough in most cases. Everything else can be hammers/gold.
3. I'm not "ignoring" anything. I play a lot of Liberty games and can actually back this up with experience--the whole reason I've been posting game results in this thread: to show it actually being done.
Yes, you have more hammers, but you're spending a great proportion of your total hammer output on buildings to get the same result.
But it isn't the same results. Developed cities produce a surplus of gold and extra science. Yes, it takes a total of 40 turns to build 4 10-turn factories and 80 turns to build 8 10-turn factories... so what? That doesn't mean anything. The only thing that matters is total amount of beakers (in relation to tech cost, of course), gold, culture, etc.
There's a sweet spot, like it or not, and it's closer to 4 than it is to 15.
I've never once thrown out the number of 15 in this entire thread. I've mentioned numbers of 6 and 8 mostly, and I've even mentioned that after a certain point (I'd estimate in the 10-15 city range depending on a number of different factors) it becomes too difficult to break even and no longer worth it. Except for random puppets in a domination game or something, of course.
I've also acknowledged that 4-city Tradition is A.) Strong and B.) Has an advantage over Liberty through Monarchy.
My comments in this thread have been mainly focused on
-replies to comments claiming anything beyond 4 cities doesn't work. False.
-Liberty cannot be competitive and or work on Deity. False.
-Liberty needs buffs because it is so far behind Tradition. False.
I *really* feel the difference. I'm spending such a larger percent of my gold and hammers on buildings to manage happiness, and my tech costs are way up. (+50% at ten cities!)
You are probably doing something wrong. For one thing, it should be 45% (I'm 99% sure the initial city doesn't influence cost, it is each additional city that raises it by 5%). And for another, you end up with more science than the penalty takes and end-game is when Liberty really takes off resulting in quicker tech rates than 3-4 city Tradition. My guess is you expanded beyond your means which forced you into needing happiness buildings sooner than convenient in combination with too low of population sizes to abuse GS slots without sacrificing production. If you have a fail game you don't demand game adjustments, you analyze first and see if there was anything you could have done better. I'd argue for all the people saying they have fail games with Liberty, nearly all can be attributed to player mistakes. If anyone thinks differently, feel free to post the saves.
Liberty is missing one thing that would really help: Reduced tech penalty per city. (Make it 2.5% or 3% instead of 5%)
Not really needed, IMO. This change is one of my favorite. It sucks for early puppet empires (pretty much killing that strat), but it does what it is intended to do, and it does it well: curbs late-game snowball effect.
And NC is just way better than an academy. In the long run, you get a lot more than 8 beakers/turn out of the NC, even with liberty.
It is just to bridge the gap due to later NC. Once you hit mid-game, the benefit of NC begins to diminish (cities with observatories get the same benefit along with a larger bulk pool of beakers). If you get lucky on mercantile quests or whatever, you don't even need to burn it on the GS and can use it on something else. Not sure I agree with burning a GE on NC. I know some of you do it, but I cannot imagine it works out in the long run.
I'm not knocking Liberty, I'm just saying Tradition outperforms it if the AI lets you settle where you like. (Which happens way less often post patch!)
Nor am I knocking Tradition I'm just against knee-jerk changes to a game when there isn't experience to back it up (much less common on these forums, although still a personal pet peeve of mine). Judging from some of the comments I question whether some of you have any experience with Liberty at all beyond attempting a small number of games and trying to play it like Tradition, then simply writing it off as useless.
Like I said, post the fail games. I don't say this in a "macho internet badass rolleyes way of "throwing down" but purely for evidence one way or another. If it turns out Liberty is indeed too weak and cannot work and in need of changes, I'm all for it, but it hasn't been my experience. Give me some evidence to work with, because armchair theory-crafting isn't enough and what people are claiming, I just don't see it in the games I am playing.
