A question about intertemporal price discrimination
Airline seats are often priced lower when first released and the price can rise, especially as you get closer to flight time.
The effectiveness will depend on the market, pent-up demand, and thus substitution effects. There are not many substitutes for a given video game while for a flight there are many substitutes such as flying earlier or using another carrier. The intertemporal aspect comes in since people buying later were not able to plan ahead and so pay a premium versus people who did plan ahead or are able to fly later.
For something unique, a low price early on might be justifiable as generating publicity; however, I doubt extending that low price to all early buyers would be optimal.
