To go back on the Lucas thing:
It's not like he and his game is even well received in his own country, with the handful of people who bought it. The Japanese have had a mostly mixed reaction with Mother 3, and I don't blame them. M2 is clearly held in much higher regard. That is why to this day we are getting yet another run of figurines and they are exclusively M2 characters, a game a decade older.
I can't think of a single franchise represented in Smash Bros more important to me than Mother, and I don't want Lucas back at all. He felt like a patched Ness. What a filthy insult to give us Lucas, a character who is more or less the same archetype as Ness, who was preceded by Ninten. Why not Loid/Jeff/Duster, or Ana/Paula/Kumatora? They are main characters who are of the tool-user and PSI specialist archetypes, serve similar theatrical roles. Granted the M3 characters by design were designed to shake up the formula, but still.
Of course Ness and Lucas can be made more different, but why? It would be like having Marth and Eliwood as the Fire Emblem representatives, and making Eliwood into the powerhouse instead of having Ike. Granted, Lucas is the "mainest" of characters, but In M3 out of all the games is when you spend the least time with him compared to Ninten and Ness. Let someone else represent a new play style that can do so more organically.
For what it's worth, I liked Lucas, even if I didn't appreciate his game too much. He's a sweet kid, just among the bottom of the barrel of Mother characters I would want for the purposes of Smash Bros. It bothers me that a lot of the people who defend him haven't even played at least two, sometimes not even one, of the Mother games. A lot of people just want him in Smash Bros again because he was there once, like with Roy supporters.
