Well after checking the additional info on both games, I can tell you that the upcoming Civ 4 will win hands down as far as replay value is concerned, over the also upcoming AOE3. In addition, I also found out that Civ4 will be the most moddable game out there, you can virtually change anything and everything short of the source code for this game. That speaks volumes, since we all know that the more moddable the game is, the more long-term replay value it has. Civ3 itself was pretty moddable, but Civ4 is basically the new king of moddability. Can't wait to see what the modding community does with the game once it comes out later this year.
I was perusing the forums for the Civ games and can you believe that there are a lot of 50+ men playing this thing? And a lot of them have been doing so since the first Civ game came out around 14 year ago. The oldest so far is an 82 year old fellow who's been playing it since Civ2. I had the first one when it first came out, but I was more into the racing/combat scene at that time, and the game didn't appeal to me. Maybe that's what happens with Vivec, the gameplay doesn't appeal to him. The Sims is the top best seller
This is a game that requires patience & planning, it's like eating an expensive meal, you have to go slow in order to enjoy the taste to its fullest. Back when I first bought the original Civ, I didn't have the patience for the game, so I played for maybe 2-3 days and gave up on it. After reading the posts at the Civ forums, and seeing that most people fall into the 20-40 age group but there are also a large base of 50+ yr olds playing this thing not for weeks or months but long years, I have decided to give it another whirl, but was also interested in the AOE3 since the game looked fantastic as far as graphics, but we all know that gameplay is the variable that makes/breaks a game in the first place, and Civ seems to be king in that area. From what I've gathered so far, no 2 games play alike even if you make the same moves, it won't play the same.
