I didn’t go through all the comments here, but let me give my overal opinion.
Best things about Echoes is it’s stellar presentation.
Artstyle, music, overall feel. All is done so great. It’s fun to jump in.
But what’s even better are the characters and especially their voice actors. Personal favorites are Mae, Lukas, Berkut and Clive. But pretty much all of em do a great job.
The characters themselfs are very down to earth and likable.
Not many super deep characters (except Lukas and Clive if you dig in the DLC and their supports), but a lot of just likable characters.
Which is probably best.
It kinda pays in it with the overal plot not being that special. It’s fine, won’t say much. And does have some neat ideas of gods versus man, but overall avarage for FE.
FE 4, 5, 7, 8, 9 and 10 all have a better allround plot in my opinion.
And the second problem is the gameplay. While it being differend from normal FE games can be fun, Echoes can feel tedious at time. With large boring map, not a big deal of costumization and dungeons that really aren’t fun.
Overall for me the good far outweigh the bad. But it’s not perfect.
Certainly think it’s not the most replayable of FE games.
