That's not true with higher difficulties and non small/duel continents. On higher difficulties and bigger maps you may easily bring down one civ with horseys but by then other civs are very likely to be protected by spearmen and/or pikemen that counter horsemen. Then you have to suffer heavy diplomatic disadvantage for the rest of your time in the continent.
I am more then happy to upload the saved game for you...you can see for yourself that in CIV V this can be done.
Here is my savegame.
Here you see the almighty French "Armee" (mind you i have nothing much else...maybe 1 spear somewhere)
B) you are familiar that the horsemen in CIV V is a overpowered unit and that this "horseman strategy is explained in detail here in the forum ?
The two things I love the most about Civ 5 are hexes & the strategic resource implementation. Also, the graphics blend beautifully with the hex style and the intro video is some of the best CGI work I've ever seen in a game.
Yep, that's pretty much it for me too. City states could have been one, but the way they have don it...meh
