JMich: Which questions specifically?
amok: "Was the price of the game irrelevant to those buying?"screams out straight away :)
Not necessarily. For example, I mostly buy games when they are discounted. I don't really care for their initial price. The only games in this experiment that were discounted were games I already had. So for me, the price was irrelevant, it's the fact that they weren't on promo that prevented me from buying them. My current buying habits do show that, so while confirmation would require an interview/questionnaire, it can be interpreted like that. Thus the time needed for analysis.
amok: Any question about the wishlist is problematic, as it is very subjective what people use the wishlist for. I never use them at all, for example. However, this do not mean that there are not any games here I want to buy when it drops in price / when I feel like it. Interfering anything on the value on the wishlist without any further investigations are , I would consider, a little pointless.
And again, it can't be a simple "Did he buy the game because it was on his wishlist?" check. They do have to see how often one buys games he has on his wishlist, how often he buys games not on his wishlist, and see how the experiement games fit with that behaviour. Which all adds up to more time needed for analysis, thus the 2-3 months I predicted.
