Once again, you prove how stupid you really are. Seriously, no one can be wrong thinking a game is better or worse than another game. Please, use your brain if you have one...
A very small minority prefer Civ 3? Looking at the activity in the Civ 3 and 4 forums right now, 1/3 of the people in a Civ related forum are in Civ 3's subforums. That is not a very small minority.
Probably a third of the people who had significant problems with Civ 4 when it was released.
Getting rid of corruption came at the cost of being the ruler of an empire. Civ 4 you're the ruler of a small number of cities or you're crippled. You can't have a big army or you're crippled. You can't remove all WW at the expense of other things in your empire even, which is a huge loss for those wanting to be able to stage huge battles between massive armies.
The Civ 4 graphics make me want to vomit, that's how bad they are. Plus, 3d graphics aren't easy to mod, so you can't replace the graphics with others you would prefer unlike in Civ 3. In my opinion, the Warlords expansion was the worst game ever made by Firaxis. Adding a completely unbalancing unit, a new Great Person the AI failed to use wisely and Vassal States which didn't work in anyway like they were intended? Great expansion...
