Since I'm not willing to fork out the money for PS3 or Xbox 360, I've got a Wii and a DS.
So, I was a little sad that it didn't come out on the Wii.
However, I rushed out to get the DS version.
(Twice actually, since I found two different release dates.
One said release was to be the 7th, another said the 9th.
I got out on the 7th, but it wasn't released... and I wasn't able to check for it again until the 11th.)
I have played two rounds so far, and won both of them.
However, the only reason I knew what I was doing is because I have Civ3 and Civ4. I blindly fired off buildings and wonders, and the occasional unit (I'm not very aggressive).
Information about buildings and wonders (benefits) is only available on the build list... as far as I can find.
I see there is no Civolepedia in the DS version.
Selecting units to build can be odd, since I have to scroll over a unit repeatedly to get it to show the stats.
I played on the lowest difficulty level, figuring I'd get a feel for the game before trying a tougher level.
Both times, everyone... I mean everyone, declared war on me.
I did manage to stave them off, taking their cities until they backed off.
I'm worried about trying a tougher level, because if on easy they have a larger military then me and keep up with me on research, I wouldn't stand a chance on tougher levels.
(Yes, I realize that the difficulty level is just the amount of advantage I get over the AI, but I didn't see any advantage that I could determine.)
Overall, I like that it is a portable version of Civ.
I will keep playing, trying to learn how to be more aggressive...
But, when it comes down to it, I prefer Civ4.
... I just wish I had a computer that could handle a map larger then 'Duel'.
(CPU: 989 MHz - RAM: 768 MB.)
As a note, I don't use the Stylus (touch controls) to play it on the DS.
Actually, I don't use the Stylus much at all... hehehe.
