Collecting NES games isnt that hard. You cazn find games at many places. i ussualy go to Gamestop, They have allot fo games, but prices are kinda high sometimes. Thebest place to find NES games is at flee markets. I have also gotten many NES games buy just asking them. I asked my friends and got ober 20 games just liek that. garge sells are also a goof place to get games. Allot of games I have gotten from gargae sells do not work to well, so you might habve to clean them 1st.
