(The "progression turns into a discount", however, indicates a hidden agenda. During both of those Challenges, there was an option to buy the rewards you haven't gotten yet. The deal remained on table for a few days after the marathon was over. However, the stages you have completed were factored in as a discount for the package: each stage was additional -10% [The stages were progressively harder, but completing them all resulted in -100% discount - i.e. for free]. From one side, it's a marketing move based on Sunk Cost Fallacy, As for those who were going to just buy that premium tank anyway; from one side it could let them earn up to 90% discount, but from another side there were also stage rewards (consumables, in-game credits, boosters, etc) in the package and their cost was factored in, so people who wanted to buy just the tank would end up playing about the same cost if not more.)
The "progression turns into a discount" strategy is quite clever. It encourages players to complete stages, offering discounts on the final reward. This approach can motivate players to engage more with the game, aiming for the 100% discount. However, it's also a smart marketing tactic that plays on the Sunk Cost Fallacy, making players feel invested and more likely to spend.
In terms of affiliate marketing keyword research, this strategy can be applied by identifying keywords that resonate with players' desire to achieve and save. By targeting these keywords, marketers can attract an audience that's already interested in gaming and looking for ways to maximize their rewards. This can lead to more effective affiliate marketing campaigns.
