Why can't I gift to others after that?
If it's as simple as 'Because they could return it to me' - then just code it so additional starter packs could only be gifted, and no additional started packs of the same type could ever be opened by the same player.
I've started several players in the game, I've friended several new players too, and it'd be useful if I could help to give them a boost at the beginning of their adventure.
Just sayin'.
The problem with society these days is that no one drinks from the skulls of their enemies anymore.
