Setting aside the clones, I'd say if you were comparing Marth and Ike directly, Marth is the more interesting of the two, as they're both fairly generic swordsmen. But Marth is the "agile" one while Ike is the "slow and strong" one, which makes him inherently interesting.
I don't believe that. But I also don't think they're disliked because of their movesets OR their characters. They're disliked because they're FE character 6 and 8 in Smash. Ike is liked more because he was only number 3.
Basically, each FE character is hated more than the last because people don't want more FE characters! Not because the newer characters are worse than the old ones.
I honestly feel you're right on both counts.
If Ike had been dropped like Roy was and Corrin was the 3rd FE in Smash 4, more people would be fine with her..same for Byleth if they were only the 4th FE character in Ultimate.
Granted, then we run into the issue with playable characters in Smash..they'll always have their fans, whether they are included in the game or not. People would ironically be calling for cut characters, even Fire Emblem characters, to return to Smash while simultaneously bemoaning the amount of Fire Emblem characters in the game. In short, a lot of these people want the familiar and will shun the new because its not the character they liked before.
Wow, you somehow managed to misunderstand the pre-Awakening FE fandom, the Awakening fandom, the Fates fandom (if it exists, I'm assuming it has to), the Three Houses fandom, the pro-FE Smash fandom, and the anti-FE Smash fandom.
I think you're pretty much the only person in the world who thinks that.
I'm actually Pre, Awakening, Fates, Three Houses, and Pro-FE in regards to those fandoms and I think he pretty much nailed it.
I honestly believe that Roy nor Ike would be that popular had it not been for their appearances in Super Smash Bros. Most people will tell you that Roy is one of the less interesting Lords and Path of Radiance & Radiant Dawn didn't sell that well, so his popularity could easily have gone to someone else like Hector or Ephraim.
And yes, Fates does have a fandom..its more popular than people like to give it credit for..not to mention a lot of times you get criticized if you admit to liking something that is seen as 'bad'.
