"So, you've saved up your money and bought you a nice, shiny Vita. You've paid the slightly-expensive price for one of its proprietary memory cards (which I fully expect third party memory cards to come out soon too at $10-15 cheaper). Now it's time to buy some games for the device. So how does one go about getting them, you ask?
When you get to this point, you've got two options: 1) Digital copy via PSN & 2) Hard copy from brick-and-mortar retailer (WalMart, CostC0, GameStop, etc.) So, now you're saying, "But I could do that on the PSP." Yes, that's very true, but there's a couple differences worth noting about the Vita."
