I dunno.
Everybody brings up Itunes and mentions music. It should be $0.99 or $1.99 a song, but not more.
I think Itunes and music is a poor comparison to downloading games, however lets do go that route and compare just for a second.
People are downloading music that has very little value except that person is attached to the song and enjoys listening to that song. They in essence paying for the ability to listen to a 3 minute song over and over...or until they get tired or bored with the song. Many of these songs on Itunes are old music that you can probably buy used at music stores for cheaper than that $0.99 price per song for an album.
Now, lets talk about games. Old games are still being played and remade on the net everyday. Most of these games for full versions you must pay for the game. Usually much more than $5.00.
Old NES, SNES, and Nintendo 64 games. Will probably bring old and new players at LEAST an hour or more play time for the first run through. With the ability to play the games over again, and allow friends to play such games over again and with you. (Just like I-tunes.) However, where I-tunes makes you pay 0.99 for three to 4 minutes. You are Demanding Nintendo charge the same amount for an infinitely better value. 30 minutes of music would easily cost you over $10.00.
What more you are not just buying music with a game. You are getting an experience complete with media, sound, interaction, competition. There is alot of work involved. Yes, these IPs have already been payed for and have already made money for the company, but so has the OLD MUSIC.
And really $5.00 is not much to ask to replay Mario Brothers again as many times as you want. Go to an arcade and $5.00 will buy you 5 turns on your favorite racer or shooter. Go to the used games stores and try to buy Chrono Trigger or Super Mario RPG for $5.00. These games are more expensive than that.
I still consider it a value, before you even begin to tack on the idea that Nintendo is giving you free Wifi Revolution and DS connection instead of making you pay like Microsoft. It is still a value before you realize that these downloads are the only thing keeping you from having to pay for online and watching your favorite game company continue to loss money with an expensive online plan.
So, whatif the games are MORE than $5.00. What if they are $10.00? When does it become too expensive? Simple when people aren't willing to pay for the downloads...when people feel they are unjustly being ripped off.
Perhaps $10.00 for a NES game is too much. However, I will contend most buyers will still see Top SNES games and Rare SNES games a bargain at $10.00. Nintendo 64 games as well are a bargain at $10.00...and the reason is that the original IP no matter how old it is, and now matter how dated you think it is. Still has value to the fans that desire to play those games.
I think being able to buy 1 average next generation game for $60.00 isn't nearly the same value of getting 6-12 AAA classic titles from my favorite systems in the past.
