As of right now, they are all overpriced. Don't buy ANY of them.
Saints Row the Third is a 18 rated game. I would say it is not appropriate for ages 13 and would of personally rated it as a 16. Rating of content to greatly subject to opinion and relative to individual consuming it. So basically its up to you if you think the content is appropriate the teens. You will be the best judge how the content will affect them.
There is lot of new content and games on the Nabi Jr. which your child may enjoy. Nickelodeon offers lots of downloadable content and games which are appropriate to all ages at www.kidsreen.com.
They each have their good and bad points, i dont think there is a best or a worst but withever one you personaly like best since each of them is a tad bit differant.
Saints Row the Third is not a web-based game. You buy it either digitally from a participating retailer, or via a disc from participating retailers. Look into places such as Best Buy or Wal-Mart.

actually it has already been released. Although the real game will never come out on the DS, there is a variant called "Call of Duty:Mobilized" it has a different storyline but its the best shooter for the Nintendo DS right now.
MineCraft all the way!!
Minecraft or terraria

that depends on what your using the computer for. if you mean to play games than the PS3 is the best because the games are mostly the same as a PC, its half the price of a decent gaming PC and it has more downloadable content.
Saints!!!! WHO DAT??
