When I pre-ordered the digital deluxe, I specifically justified breaking my rule of pre-orders and digital deluxe packs because I trusted this company to make it worthwhile. I was concerned when the viking scenario pack came out because I wouldn't have normally purchased a dlc like it, but kept faith anyway, once again based on the reputation of the company and my personal experiences with Civilization games. Now that I've saved $4 US, what amounts to maybe two cups of coffee, I don't really feel it was worth the anxiety or the leap of faith, especially when I could have waited and bought later editions at a discounted price.
I am not a lawyer, so I don't know how all the legal stuff will resolve. Honestly, I don't really care. I am a customer, however. If I assume everything is above board legally, I can conclude the following: I saved two cups of coffee, and lost a lot of good will for Firaxis (or 2K, or whoever; it really doesn't matter). I may continue to purchase products from this company; I may not. However, I certainly won't ever give them the benefit of the doubt again. If they want to continue to make pre-ordering an attractive option for customers, for whatever business reason, they have a long, uphill journey ahead.
