Need to ask u guys something about Vita. Let say I buy one physical copy of Vita game, can I copy it to my Vita memory card and run it without physical copy? Also if I buy vita games online, how many people that I can share on the game?

From what I heard the price of digital is a bit cheaper than physical, you can sell the retail copy but you can't sell digital copy. Looks like retail copy is the way to go.
