Because those who do play it never turn it off because of the long load times, they leave in between turns to do other stuff, or alt tab out of the game and leave it run in the background. I know several people who did this.
I don't know anyone who does this. The people I know play the game instead.
The amount played on Steam is an indicator of the game's succes, but also the amount of sales, which is about 0.9 million in America and Europe alone. Which is one thing, but even more interesting is the fact that it still sells quote good every month and it's still a rising line (so it aren't all disgruntled pre-order people

)
Yah.. and it would probably closer to Civ-Facebook then Civ4. In which case its better if the series just died now and saved itself further embarassment.
The only way I see the series saving itself is 2K giving the series to another set of developers who are fans of the earlier games and cutting Sid and Firaxis out compeletly.
First of, Civworld is a different branch of the series, just like Civilization Revolution is.
And secondly you could face the fact that for a lot of people Civ 5
is really enjoyable. And even Civworld is really enjoyable for some people (not me, though).
Like the above poster, I'm sorry that you don't like the game, but there are a lot of people that
do like the game and it isn't a bad game at all.
Maybe not the game you (or any other of the Civ 5-complainers, I'm not specifically talking to you) would want to see, but that doesn't make it a bad game.
I also love CiV, and don't have any turn-time problems, but I hardly play huge maps (I only experience long loading times in the late game on huge maps).
No one here has any proof, nor do I, that the DLCs were made after the official game was released.
Neither does anyone have any proof the expansion packs (for Civ4 or possibly Civ5) were made after the official game was launched
The truth is that if a expansion pack is to be released sometime at the end of the year, then you have to at least consider whether or not you are willing to pay possibly 30 US dollars along with all of the DLCs that you had bought as well as the game (60 US dollars if you didn't wait for some Steam deals).
If the expansion is worth it I wouldn't have any trouble paying more money. I've bought CiV, and all the DLC (outside the sales) and it was worth every penny. So I wouldn't mind paying some more,
if the expansion is worth it. And otherwise I'd wait for a 66% or 75% off sale.
