Fab, I *own* over 120 NES games.
(A few years ago, a local game store got bought by another store. I was there the day they were doing inventory. The guy doing it was all flustered at having to count all the NES game titles, so he told me I could have any I wanted for $1 each. I tripled the size of my collection that day.)
The ones I keep coming back to are the Zeldas, Final Fantasy, the Dragon Warriors series, and TMNT 2 & 3.
