This thread is pretty funny!!
I voted, of course, as did most, that my highest scores were from conquest/domination. Which they are.
I think that "rewarding genocide" was not exactly what the designers, all the way back to Sid, had in mind. But as has been said, the combination of the corruption model and culture effects certainly makes razing cities the smart strategy to play ... and at harder difficulty levels, not just to have a high score, but to survive.
But more germane to the poll ... isn't this the way its been in RL, more or less, through the ages? He who has the biggest baddest military tends to assimilate the weaker ... swords kill much faster then ideas do. Yes, the power of ideas have grown able to tear down dictators today ... but only after the People have a direct personal interest, usually, in that happening ... like personal survival, avoidance of starvation, etc. Of course, if we look at some countries in disarry, like Liberia or Somilia, it isn't clear what ideas are in charge ... but if someone has a gun pointed at you, you KNOW who is in charge.
The funny thing about this thread is the way everyone (well, most anyway- not "everyone") rationalise these less savory concepts like city razing or starving of foreign nationals. No one wants to feel guilty, but they DO want to win the game. So they raze or starve, and rationalise it. (Of course, some glory in it: phillipe, more or less: "When my cities are in rebellion, I nuke the city ..." LOL!! ROTFL!!!) ANYWAY, let me comment the way a friends cousin did. This was many years ago, in the late 60's, and my friend and I were busy raging blitzkreig with an old Avalon Hill board game when his older cousin, a honest to goodness hippy and war protester, walked in. Stricken by guilt, we tried to ratioanlise playing a "WAR" game. He laughed and said no big deal ... he didn't see any blood anywhere ... and went on his way.
So my point folks, is its a game, and let's enjoy it ... if your significant other will let you ... without guilt.
Civ ON!
