Interesting gauntlet.
And once in a life on my preferred speed.
So, since i still own the HoF first place with some Space game, this is obviously my favourite VC.
I spent a lot of time generating decent maps.
Often a very nice start to discover in few turns i was isolated in a small island with hardly room for 3 cities.
Dozens of games started and abandoned at first glance (maybe i was wrong) due to indecent starting locations.
Well, i managed a 1873 victory, but lost the initial save, probably in a clean up of all the rubbish the map generator produced. So no submission.
Then, i've seen the ICS driven dates, so i'm trying to adopt this strategy, possibly with some variation.
I discovered that the success with the GLib is, or can be, determined by the opponents. I always set them to random, but noticed that Ramesses and Cathy (at least) love to go for that, so if you have them on your game, you're toasted.
In one of the games i'm trying now, i got all good warmongers, including the newly added Gengis, so this is probably why i could have built the GLib around turn 90 for education, no bulbing. By that time you don't need any SP. Building both Oracle and GLib in the same city (usually your capital) a Sci specialist at work guarantees a fair early GS to bulb Astro (far more useful than acoustics) when you got all the prerequisites. The only expensive one is compass, sailing and optics are very cheap.
I also noticed that Hiawatha loves SH. In any game he goes straight to that wonder.
