- they want repeat players (users)
- they repeat a formula that sells
- when it doesn’t, they look to “adjust” it with something new and preferably cheap
- they give free samples to spread word of mouth
- they try to lock people into their environment
- they always want people to chase the next high
- looking for ways to keep you hooked on something for as long as possible
- they try to use their formula in all their products
Yeah, they are more apt comparisons where the target market is built upon consistent small (or large) payments that are in a business’ best interests - like in-game currencies (chips in gambling sense) are used to obfuscate the value of what a player is spending money on (which falls into one of the many psychological tricks you mentioned)
