Unless the reviews are negative, I will buy the game during the first week. I won't pre-order, having been burned when Civ IV didn't have enough copies on release. After a couple days, I had to cancel my order and buy it at GameStop. Later, I was seriously disappointed with the vanilla version of Civ V, and the reviews would have deterred me from buying it. I was burned again when Steam discounted BNW the day after it was released. I would like to pre-order, as encouragement to Firaxis. But I would feel foolish at this point.
