A "SNES-talgia" attack

So recently i was playing some blops when I thought about it for a second and realized that i was sick of current gen games, I had a hanker in for some old school stuff, so i headed over to Ebay and sure enough made some purchases. The bulk of which can be seen here:  

Needless to say, its been a refreshing break from newer gen titles. I am about 3/4th's through Super Mario World, very addictive, could play that for hours and a couple hours in to Final Fantasy 2.  Needless to say, I'm looking forward to going back through these classics as an adult and see if i can see things a little differently as opposed to when i was in the 9-13 age range. How often do you guys go back and replay older games? Any recommendations for the Snes?
