This is your list. That I think some things may be missing is irrelevant, but it can be a conversation starter.
That you have a duplicate means you can cram more of your favorites in, if you like.
Which was your favorite?
Definitely Balloon Fight. The control scheme is perfect. Two player coop. Simple but fun, and with the right challenge.
I wish it had more variety in the level design.
What are your NES favourites?
