Either on Facebook or on Second Life, one can spend alot of money by buying virtual gifts and necessity.
Whenever I want to send a birthday wish to a Facebook friend, the option of gifts come up but these "gifts" cost real money. I also know I used to spend money on buying virtual protection on Mob Wars. So what do you think about this? Zygna, maker of many of these online games on Facebook, have made millions just from selling virtual gifts. What do you think?
