that would be a stupid thing to do economically.
PTCGO=online cards
ways to get online cards
sell x amount of packs which gives a player x amount of packs online
sell x amount of tins/bundles/specials
TPCi/PUSA earns more money via selling codes in packs than it would by selling only online cards for a specific online market.
also,this would undermine the TRADING part of the pokemon TRADING card game.
example:
-player A is a teen whose parrents pay for his cards,trips etc.
A decides to play online,gets his parrents to buy him online cards,makes fun of other people who don't have many cards online
-player B is an "adult" who works for a living,pays bills,play PTCGO occasionally but not enough to invest a large amount of money,but does play the trading card game
-player C is a "normal player" who pays for his packs by himself,uses PTCGO as an additional part of the game and enjoys the trading part of it
So all in all:
-player A-doesn't want to get random cards,doesn't understand the "spirit of the game"(fair play,trading&making new friends,learning something new,having fun while playing...),used to getting everything he/she wants,just gets everything he wants from his parrents
-player B-someone who gets the spirit of the game,uses trading to complete his decks,a part of his/hers collection&knows how to trade quickly and efficiently with no need to get complete sets at once
player C-knows the spirit of the game,understands how trading works,does quick&efficient trading with the few packs he has got
Examples of such players online(my list) for some of you who might know them
player A-many of them,but i just ignore most of them
player B- "32914" on PTCGO
player C- "AlexManectric", me aka "podlasica" ,"matthew69", "EtownMaster" and some others
there may be other mixed categories but this is how i see it
jmho though
EDIT:
@bullados
Gems will be a payable currency for those players who will want to spend their money on avatar items such as deckboxes,sleeves and such.Gems will be tradable
@dld4a ,if you want to you can always get full sets for x amount of online boosters,i don't see why real money trades would have to be involved.
