I love(d) pokemon snap!
I love pokemon snap as well...I could play it over and over just to try and get better shots.
As for the gameboy games, I only played Blue. I got all 150 one time...I wasn't aware that Mew was in the game until now. After the first games I didn't really see the point, same game different pokemon (though I have been told that the newer games offer more depth). They were great games, they really defined the original Game Boy.
