List of overall favorites that I feel contribute the most to Brawl
1:Mario, because hes the gaming icon that started it all, with lots of representatives and many Mario specific items.
2: Pokemon, because they not only have 4+ representatives, but they also brought in Pokeballs one of the items that made the whole Smash Series Famous.
3:Zelda, lots of good characters, almost as much of a legend as Mario himself.
4:Donkeykong, because he really isn't one of my favorite characters and hasn't had a game I considered good since Donkeykong 64.
5:Kirby, cause he is a highly unique character with games I love, eat people then use their powers...awesome.
6:Starfox, although its only real claim to fame is Starfox 64, great concept, contributes a lot to smash.
7:Metroid, Because I never really gave it a chance and never played one of the games for more then an hour.
8:Fire Emblem, it really contributed a lot less than Metriod, although I have grown to enjoy the fire emblem games, Metriod has seniority and much more representation in the gaming community.
The rest all have only 1 character and didn't contribute much to Brawl, but are none the less great games.
Overall my Favorite Franchise is Pokemon, because it is really its own kind of game, an rpg with lovable characters... hate pikachu to death tho.
Mario Contributed the most to Smash.
