Turn 300 of our multiplayer, all civ, marathon, giant map. So far so good as Canada, just coming to the end of back to back golden ages, being able to build nicely on tundra (and being able to buy tundra tiles at 50% cost) has allowed me to expand and be reasonably isolated from external pressure. The AI nations (all deity level) are doing ok though many fell early, as they often do on the all civ games that we play. The guy who is playing as Maori is doing very well indeed, the sea based start allowed him to choose a strong start location. The players (there are 7 human players) of Mali and Hungary are also doing very well.
