Whereas some video games give you a Wallet of Holding in which you can eventually stash more money than you ever could use, other games aren't so generous about letting you have the money you need to buy that really useful item, no matter how good you are at beating the coins out of Money Spiders. When there are useful items on sale for more than your standard wallet can hold, you need a Wallet Upgrade, which can be any sort of item (which you may have to buy at no small cost) or even an in-game event that raises the amount of money you can carry on yourself. Related to Cap, which usually describes a hard limit.
- Most later games in The Legend of Zelda series have wallet upgrades that let Link carry more rupees.
- In Golvellius, Bibles increase the maximum amount of gold Kelesis can carry.
- The Guardian Legend has Red Landers.
- In BioShock 2, researching thuggish splicers can increase your wallet cap from $600 to $800.
- In Far Cry 3 and 4 you have to hunt animals and use their hides to craft better wallets and the last upgrade requires the hunting of rare animals.
- Drip Stat, an MMO Idle Game to advertise the DripStat Java server monitoring tool, initially limits the player to five "bytes" (clicks) of capacity. Clicking produces no effect after this point. The "Drip" button exchanges bytes in the bank for bytes of capacity: clicking Drip with 3 bytes clears the bank to 0 but adds 3 bytes to capacity. During the tutorial, the capacity quickly doubles to 10, then 20, then 40, until the tutorial ends around 160.
