I dont whish to amend my statement civ 3 was 10 times the game civ 5 is, if you cant see that its just because you like simple games.
Here we go. You claim that Civ 3 was a great game for its time. My response is that Alpha Centauri was published earlier and was ten times better. Both bear the Sid Meier name, both have the same basic idea -- build settlers to found cities.
For its time, Civ 3 was a lousy, rushed, piece of crap that built on none of the good ideas found in Alpha Centauri. It is not 10 times better than Civ 5 for its time, but it's useful to examine the two in parallel because both were preceded by great games.
Let's look at the gameplay Civ 3 brought to the table.
Rex Like Mad
Establish a settler factory and churn out the cities. Cram a city in every available space. No, really. There are articles on establishing Settler
factories so you can churn out the greatest amount of settlers in the least amount of time.
Kill
Want to rush Wonders? You have to fight several wars in order to generate a great leader to rush that Wonder.
Want to build buildings? Sorry, corruption's going to nail every city past the first few, but you have to found those cities anyway because that's what the AI is doing.
Never mind that the game actually punishes you for building most of those buildings in the form of building maintenance.
Want a space victory? Sorry, all the aluminum's on the other continent. You CAN'T build a spaceship.
Want to cultivate good relations with your neighbors? Forget it. Diplomacy is completely hidden. AIs will traipse across your borders all day and declare on you for complaining. AIs will declare on you if you send a simple boat through their sea waters in return. However, you can ROP rape whoever you want, and in the end, it's more profitable to do that than to have a neighbor.
Civ 3's gameplay was simplistic to the point of stupidity, up to and including "toss a coin" battles. Compare it with Alpha Centauri, which, as I mentioned, came earlier, and it's dumbed down with a vengeance.
And yet it got its War Academy. Civ 5 deserves one, as well.
