I've been waiting for Civ3 for years. I play Civ1 or SMAC every other day (Civ2 is too hideous visually to tolerate), and always with cheats turned on because I want to have fun.
Well, with Civ1 I'm forced to use a trainer, but...
When I sit down with a computer game, before I even open the package I have researched the cheats. I prefer to treat a game as a toy rather than as a means to boost my fragile ego. It's fun to lay down a stack of nukes in the center of your opponents continent and send them flying. It's fun to grow an empire without worrying over resources, just to watch it develop.
Today, the day before release, I learned that for some foolish reason they've removed the in game cheat mode. I promise you that this will impact sales. My friends all play Civ2/SMAC with cheats on. Often. It's what you do when you're bored and in my peer group. When I relay the news of what I've found, none of us will likely buy Civ3. Firaxis has robbed us of our potential fun because a number of internet blowhards have decried the presence of a built in, comprehensive cheat mode.
Guys, if you don't like the cheat menu, don't use it, but it's wrong to infringe upon the happiness of the casual user with your mousepad machismo.
It's just a game. I don't have any desire whatsoever to be able to beat deity mode without cheating. I would gain nothing and lose weeks of my life trying to do so.
Firaxis, until some in game cheat mode returns via a patch, you've lost a customer. Probably three of my close friends as well, maybe five. How many other groups of friends will write off Civ3 as disappointing because of it? I'm willing to bet more than you think.
