I have been playing/collecting NES games since I got one in 1987-88. I have never run across a Flintstones:Surprise for sale.
Here are the games I have run across in wild in the last 5-10 years:
-two or three Bubble Bobble 2,
-two Power Blade 2,
-three Panic Restaurants,
-three or four Snow Bros.,
-two different Prototypes,
-one Gold NWC,
-one Bonk's (I need this one still, sold the first one years ago cuz I had it on T16)
-zero Little Samson's,
-zero Flintstones 2, (I still need this one, I have never seen one in the wild)
- 1/2 dozen Kid Klowns,
- 4-5 Color a Dinos,
- 4-5 Pro-Sports Hockey,
- a few dozen(at least) Race Americas.
I am not counting places like CGE. I am talking about Pawn shops, garage sales, flea markets, games stores, etc....
I actually think Jonebone is the person I would compare my list with...his list was:
If I had to make a guess, I'd go with:
1) SE
2) F2
3) Little Samson
4) Power Blade 2
5) Panic Restaurant
6) Bonk's Adventure
I might switch 5 & 6, but that is just because I need Bonk's.
