Now there are many ways for me to pay for Steam and similar popular services. Now I found out that it is possible to issue a virtual card in the United Arab Emirates. I'll try to see if it can be done.
As about the lifetime license. An annual subscription not a favorable investment for the personal purposes. I would like to have possibility of 1 times to pay and use software.
