Unfortunately, no. A āpledgeā is what you hand in to the pawn store in exchange for money.
Unless CI¬G is giving you money, what you're handing them is not a pledge. Obviously, the money goes in the other direction, so a āpledgeā in this transaction would have to be the collateral that CI¬G is handing you for the money you're lending them, and at some point, the money will be returned (with interest) in exchange for CI¬G getting their pledge back. A pledge is not subject to VAT, but to interest rates, same as with all money lending and as such, it would not increase the amount of money you give to CI¬G but the amount they are required to pay back to you in order to have the pledge returned to their possession. If this pledge transaction sounds nothing like what is happening in CI¬G's virtual goods store, then that means what we're dealing with here is not a pledge but a bog-standard purchase.
A āpledgeā where you end up giving both the money and the pledge is an instance where the pledge as such does not actually have anything to do with the money transaction, but with the promise of a transaction, should some conditions apply. That's why you pledge during the kickstarter: you're promising that, if the campaign succeeds, you will chip in a certain amount. That promise is the pledge, not the cash itself. Handing over the cash is not a pledge, it's the fulfilment of one. Handing over cash in exchange for a virtual good, even if delivery is estimated some time in the future, is once again just a bog-standard purchase.
