I did! I remember choosing Blue Lions and the last thing I remember from the game was fighting against those black-clad knights in that hidden area of the school.You MUST finish it when you get the chance! It's really a great entry to Fire Emblem. Did you ever pick a house?
I used to play Hero's OBSESSIVELY when I was like 11. It was my first ever exposure to the series, actually! I don't play it any more though only cause I don't really have time for mobile games.Ooh good choice, I'm a Blue Lions fan myself. :D It's still the best route, in my opinion (though I know not everyone shares that opinion).
A bit off topic from FE:3H, but do you have FEH? It's a really good "lite" version of the whole Fire Emblem series.
