I think some of the things said in the above replies are both wrong and also smack of elitism.
"4X is MEANT to be played in the manner that I say hur durr"
I have played lots of games that have only partial fog of war. Age of Empires 2 has a partial Fog of war option. I believe that Empire Earth 1 and 2 has them as well. Both Civ 4 and 5 have partial fog as well. Don't know about the earlier Civ's. So your claims that "having to explore the world map has always been a part of 4X" are completely baseless.
There is no "correct way" to play a 4X game. If that were the case, then what is the point of the "game setup" options? The game setup options in games lik Civ and LH is to allow the player to customize his gaming world so that he can have the kind of gameplay that he wants. Sometimes I want to play with full fog of war, and sometimes I only want to play with partial fog of war. To argue that the option should not be added because "its the wrong way to play the game" is nothing but elitist crap.
