Pooling logic is pretty dumb in this topic. Haven't played Zero Mission but given that Pokemon HG/SS aren't really the same as Pokemon Gold/Silver I'd be pretty confident ZM is pretty different from the original Metroid (that and the fact that people you know, like Zero Mission). Anyway, I guess I'll try and help this list not suck best I can.
+10 Fire Emblem 7
+9 Super Metroid
+8 Kirby Super Star
+7 Tetris Attack
+6 Super Mario Bros 2 (US)
+5 Super Smash Bros
+4 Star Fox 64
+3 Super Mario Bros 3
+2 Mike Tyson's Punch Out!!
+1 Legend of Zelda: A Link to the Past
