If Someone Who Has Never Used a Playstation Buys a Ps3 Move Bundle for $399, What else Do They Need to Buy?

It mentions that the games are downloadable. Does that mean they're downloadable free, or that you can buy them online and download them, or what? Are those good games, or do you have to buy them at stores if you want good games? And what else should you buy?

Suggestion:

controller, some games!
