On of my favorite things from Civ I was seeing a dominate nation that truly outbuilt, outdeveloped, outteched everyone. Sometimes it was my Civ (as long as the Mongols didn't ruin my plans) sometimes it was the Russians showing up with battleships and tanks to find my cathedrals were built just in time. Civ II and SMAC were similar in that you could build a monster civ dominating over half the map with serious lead in every category, even on Emperor/Transcendi. What started to get frustrating was how in Civ III and Civ IV they really tried to prevent runaway civs. Corruption and tech cost would attempt to create parity and bring down the top civ. Still on Civ IV you would get an occasional monster like the Inca's but generally you could prevent it as long as you made contact before they were already huge. What I want to know from those who have played or maybe just know from reading about the mechanics is are there game mechanisms in place that will prevent a civ from running away with the game? Can I or the AI expand and own half the world, have enough troops to conquer every remaining foe in 1-5 turns, have 10x the production, and be an era or more ahead in techs even on the hardest difficulties? Or does it get progressively harder the farther you get ahead to advance further? I want a civ that not only stands the test of time but dominates it. Even the AI built ones were cool to lose to. I don't want to lose to some lame AI that built a space ship part 1 turn before me that only had 5 cities. At least not nearly everytime. Typically someone should come out ahead and push that advantage till they dominate.
