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.
- In Golvellius, Bibles increase the maximum amount of gold Kelesis can carry.
- Most later games in The Legend of Zelda series have wallet upgrades that let Link carry more Rupees:
- 99 to 200, then 500 in Ocarina of Time and Majora's Mask.
- 200 to 1000, then 5000 in The Wind Waker.
- 300 to 600, then 1000 in Twilight Princess.
- 300 to 500, then 1000, then 5000 and finally 9000 in Skyward Sword. Still not enough? Beedle sells three additional wallet upgrades that raise the current cap by 300 Rupees each, for a total of 900 and thus 9000 + 900 = 9900.
- In Star Fox Adventures, at first Fox can only carry up to 10 Scarabs (the only wallet he has is that of his own clothes), but after helping a character in SnowHorn Wastes he receives a Scarab Bag that allows him to store up to 50. As the game progresses, he'll get subsequent larger wallets to carry up to 100, and then to 200.
- In Ōkami, money purse is one of the attributes you can upgrade as you gather enough Praise points from the characters you help, as well as the plants and animals you make happy. Each upgrade increases the current cap by one digit, thus going from 99999 to 99999999 (four upgrades).
- The Guardian Legend has Red Landers.
- In Hype: The Time Quest, not only can Hype have a wallet upgrade by completing Wellet's race during the Second Era, he can also upgrade the maximum amounds of each good he can carry once through the game, usually by completing a race or getting rids of all the bees plaguing either Torras or the forest.
- In BioShock 2, researching thuggish splicers can increase your wallet cap from $600 to $800. Subverted by way of Missing Secret in the first game, which has a four-digit display for your money despite being immutably capped at $500.
- 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.
