How much are super Nintendo games worth?
Their probably worth like about $75.00
The famous console war (Super Nintendo/SNES vs Mega Drive/Genesis) did not separate playgrounds that much. There would be disagreements on video games, but video games did not have as much of an impact on people in those days. Most of the arguing during the console wars was between game development studios and Sega and Nintendo themselves.
It depends on how many games and what kinds of games you are trading in. Three games that are usually on clearance and aren't selling fast will not be worth nearly as much as two brand new "Pokemon Platinum" games. You will get a larger discount off of your purchase for the DSi, but it ultimately depends on how many and what kinds of games you are trading in.
