A frind of mine who doesnt know much about games is selling me his SNES collection. Not many good games but here they are: (all loose, but have the cart covers)

Firepower 2000
Jurassic park
kirby superstar
mario world
tiny toons-buster busts loose
kirby's avalanche
megaman soccer
mario paint (w/ pad and mouse)
the terminator
TMNT-Turtles in time
X-men apocalypse
bugs bunny rabbit rampage
sparkster
bonkers
world heroes
star fox
metal combat (with a boxed scope cannon, not sure if its totaly complete, he also says it no longer works)

He told me some of the games dork work (maybe he needs to clean his snes or games) and hes also giving me a virtual boy system box too.

(tomorrow im just getting the 14 games, boxes of cannon and VB are too big to carry in school)

Whats a fari price to offer?

I would say $15-20, because he said i can have the VB box for free, and he told me the cannon doesnt work and some games too, and they arent all that rare. Also whats a boxed cannon worth?
Thanks!
