Actually, I'm waiting for the raging dinosaurs (PTW barbarian substitute) to show up in the predator class on a large continent map with only 1 opponent. I tried a game with them late last year and it was brutal. They're like Siphai in the Ancient Age.
I also enjoyed a tournament game recently that started at 4000BC with all techs through the end of the Industrial Age.
We so rarely get to build radar artillery, stealth planes, modern wonders, nukes, etc, it was a treat. The game went too fast, but with different circumstances (only culture victory allowed, etc), it would have been great. (Imagine Zulu or Aztec with nukes!!)
