While it is true that I did visit the game mags, we have gotten a lot of previews.
Computer Games Magazine did a really good review. So did Gamespot, Avault, and countless other webzines.
While CGW and PC Gamer didn't do previews, one has to realize that each year, 7500 games are released. To us, obviously, GalCiv is a big deal, but until relatively recently, GalCiv was kind of flying under the radar. And to be honest, until mid January the game wasn't terribly impressive looking (our multimedia stuff didn't get integrated until very late into development).
Magazines have to cater to their readers and hence previews tend to cover things with a very proven track record. I think a GalCiv II or something like that will get more attention if GalCiv is successful.
