When a video game company deliberately introduces a problem into their game so they can sell you the solution as opposed to designing the game to be played without paying up.
Solution selling can manifest in many different forms such as:
• Paying to skip
long monotonous grinds
• Paying to repair fragile equipment such as weapons or armor
• Paying for transport, so you
don't have to waste your time walking
• Paying to skip a difficult level/boss
• Paying to revive your character without losing progress or items
• Paying to progress at a rewarding pace
• Paying for increased inventory space
All of these issues can be solved very easily by
better game design and just respecting the
player's time and
money.
