Not pre-ordering. I am going to wait for more info and reviews on the full game.
I am especially interested in AI and MP, the 2 big weaknesses of Civ5.
I'm going to buy it as soon as it's available, whether I preorder is dependent on GMG or some other site offering it at a discount because the timing of the inevitable release sale is up to them.
I was kind of annoyed I went to GMG when it was 22% off but I put off ordering it and when I came back a day or two later it was full price.
I doubt they'll release info on DLC before releaseStill waiting for a reveal of the DLC attached to the deluxe edition. If they don't, I'll just 'pre-order' the basic edition on wednesday. I won't buy anything without knowing what is in it.
Finally decided, spent my birthday money on a pre-order. My husband assures me that if it doesn't run on my computer, which lacks a video card, we can find a relatively cheap card that will fit in the small chassis. (Civ V runs fine on low-mid settings.)
There was one day when the price on GMG went back up to full, but I think that was a mistake, because it's back to being 20% off again. You need to log in to see the full discount though.
