I remember most NES games starting out about $49.99 new (US).
I also remember most dropping down to $19.99 (minus the NES marques games) after 14-24 months.
The only games I ever saw new at $20 were the Dizzy Egg games where you bought the first one at $50 which came with a cartridge adapter and the "swap ins" which were different games about the size of Gameboy games at $20 each new, but here in Ohio just about every game started out on the NES at $50.
