First off, here's the excellent thread on OCC's I was mentioning:

Okay, playing on Diety is not going well. The source of my problems is this: I can't win the race to Literature. I win the race to writing - fine (well, some of the others have it, but I can use it well diplomatically). But the AI *always* gets to literature first, and builds Great Library before I can. FYI, The GL routinely gets built around 1400 AD.
I've tried to find some ways around this. I've found that I can build Colossus easily, but I've resorted to using it as a prebuild. I make sure to acquire Masonry&Mysticism at some point so that I can prebuild longer (using Pyr/Oracle), extending me to whoever discovers Literature.
Even then, I face one of two problems: 1) The AI builds both Pyr&Oracle before the discovery of Literature (ruining my prebuild, with wasted shields and Colossus consolation prize), or 2) Even despite my prebuilding from VERY early, the AI builds Great Library when I'm a few turns away. In other words, the AI builds GL at, say 1400BC, when I could manage to get it built at 1300BC.
To be honest, I'm really starting to question whether Great Library can be part of a OCC strategy on Diety. I've tightened up my routine to building warrior-worker-warrior-GLprebuild, and I'm still getting beat to the Library.
In one of these attempts, I was able to do some excellent work on the Trade Desk, to the point of being rich AND technologically even with everyone, and I'm really feeling that that is the better route. I think researching writing is about all I will ever do, since I can use it in trade and get myself caught up in the tech race. At that point, I'm guessing I'll be wealthy enough to pay my way through the ancient-era-tech race. How that will fly once I'm not ancient....we'll see. I'll certainly need a big payout from my era-transition tech. To this end, my ability to easily build Colossus will help with the cash-flow.
Of course, I'd much appreciate any suggestions.
The only other thought I've had is this (and it seems like suicide): Invite an early war with someone. Fortify Athens with enough (veteran) Hoplites that it can probably be defended (say, 5 hoplites - just an estimate). Hope for them to become elite and produce a Great Leader. I will probably enter a Golden Era from the battles being won, but even if I don't , the Great Leader can rush my Great Library. Make peace and get everyone happy from all the trading. It's inviting doom, but the benefits are there, and it certainly amounts to taking advantage of one of the Greeks' biggest strengths - the Hoplite.
