The are some flaws here tbh for one Galaxy outsold Sunshine and had the gravity concept which completely opens up level design and the water gun also wasn't a very innovative mechanic and didn't have as much bearing on the game in the end GC sales didn't help either, TP is a launch title for the Wii and seen by numerous as one of the best in the series while PH and ST although being good games have some significant flaws which hold them back and on top of that the handheld and console market operate off different traits. DD is down to the decline of the GC, it came in a time when the GC was really struggling plus I wouldn't really call the two drivers an innovation.
Metroid has never really been a high seller and often sells slowly the series isn't as accessible to many and is really relegated to a cult following, Smash Bros is much like any other good fighting franchise it stays consistent Melee and Brawl are very good games with different approaches it's here where you've missed the innovation somewhat. Melee is very aggressive, sharp and technical and a big step up over Smash while Brawl employs a more passive balanced approach, these two are like Third Strike and IV similar template but used on differing approaches.
NSMB is really the main one that stands out for selling no matter what.
