That would be my guess. I think MOST of the ones that are on there, are DIRECT nintendo licensed from start to finish... vs many others are Nintendo + company X (capcom, say for megaman, etc)
Most of those games are available on virtual console (for the Wii U as least, not sure if all will work just on the WII virtual console).
They range from $5-10 each. But lets go at $5 each. $5 x 30 games, is $150.
Plus, REQUIRES that you then have a console (Wii or Wii U) to play them on.. which everyone doesn't necessarily own.
It does say that it comes with an AC adapter. (Even if it was USB powered.. now a days.. who doesnt have MANY AC USB plugs. I have about.. 12 spares at home between all the devices that have come with one over the years.)
And as an added bonus for anyone who MAY have a Wii or WiiU already.. the controlers can be used with the systems for virtual console games.
I dont think anyone is saying this is the be all end all thing... that OMG EVERYONE SHOULD GO OUT AND BUY IT!!!
If you dont like it, dont buy it.
But there are many people that this I think will be a great little device.
People who are not hardcore games, may not own newer systems, but want to relive some of those games, show their kids them, etc.
My wife was even like.. that would be a great little thing we can bring in the trailer for the TV there as it wont take up space really.
