Personally, I've guessed at exhorbitant prices up to $25 for an N64 game.
But I think the real sweet spot here is below $5 for NES games, below $9 for SNES games and below $14 for N64 games.
These games need to be priced at impulse buy level, especially for casual gamers shopping online: it needs to be painless to buy Balloon Fighter or Lolo!
Although I agree with Pale, the promotion possibilities are interesting.
Pre-order Metroid Prime 4 and get to DL the NES original for free while waiting?
Buy a "Game Card" for $20 and get 4 free downloads of your choice?
Subscribe to NP and get a free DL of your choice?
DL F-Zero X and get a $5 off your purchase of F-Zero REV?
Buy FF:CC REV and save $3 off your DL of FFVI?
Register your Revolution with Nintendo and get a free "Donkey Kong" Download?
Download $30 worth of old games and you can get in the mail a free sneak peak demo pack for new and coming games?
and perhaps the most striking possibility of all:
Download Kid Icarus for the NES and you can also DL a sneak peak demo video for the resurrection of the series on the REV?
