Confirmations are not required for casual purchases. The amount of luck and effort required to double-spend an unconfirmed transaction greatly exceeds the value of casual purchases. Bitcoin confirmations are more akin to the months during which you're allowed to contest a credit card purchase, except instead of months, it's between a few minutes to an hour. Sitting there waiting for confirmation for a bitcoin purchase for a videogame is like waiting for the credit card company to reassure you that the transaction is now irreversible.
