Yeah Marth and Ike have been two of the most played characters in smash since their introduction. The Fire Emblem series transfer over well to smash, and aside from Meta Knight, Young/Toon Link, and Link, we don't have any sword wielding characters. Fire Emblem characters offer all kinds of sword-wielding styles and techniques, both Western and Eastern.
Plus another advantage the Fire Emblem series has is it has multiple "main characters" (MOTHER also has that advantage). In Mario the main character, maybe a handful of games aside, is Mario. In Zelda, Metroid, Star Fox, and other Nintendo series, there is only one main character.
Marth (FE1 and 3 and their remakes 11 and 12), Roy (FE6), Ike (FE9 and the latter part of 10), and Krom (FE13) also are 4 of the handful of Lords to fully star a Fire Emblem game.
Note: Fire Emblem 7 and 8 both have multiple "main" Lords. I don't know much about FE4 or 5, though. Is there a Lord who is the main Lord throughout those games=???
@ vicgur
Story, lol=??? The story is somewhat dark in Majora's Mask, but it isn't deep at all. If you put that "deep" game's story next to The Shawshank Redemption, you will get laughed at and embarrassed for calling that story "deep."
Regardless, I wasn't talking about the story. Stories don't keep me coming back to games over and over again. Only gameplay does that. The gameplay, difficulty (which is nonexistent in Majora's Mask, aside from that wedding mask quest because of bad camera angles), and replay value are much higher in the original Legend of Zelda and A Link to the Past IMO.
