Sorry if this has been asked already, I found some similar topics but they were from 2009 when the mechanism for buying the game was apparently different.
I want to buy
Machinarium for a friend but it's not clear how I go about that. If I click the "Buy This Game PC/MAC" button at the
Machinarium site it brings up a dialogue box asking me to enter my email address and then choose my payment option. There's also a checkbox that says "Purchase as gift". But it's not clear how that's supposed to work - should I put in my own email address or the recipient's? If I put the recipient's and try to pay with PayPal, will it let me pay with the PayPal account associated with my own email address? Putting in my email address and pressing the PayPal button with the checkbox ticked gives me no further clues, it just takes me to a payment page.
