The second game I played was Gaiden

After clearing Shadow Dragon, I was browsing the eShop and found 'Fire Emblem Gaiden', so I downloaded it. The first thing that surprised me was that the story starts inside a village and there's an RPG part. The village BGM is too cool (it's used in a different scene in the remake). Even though it's the second game in the series, there are characters with almost the same face graphics. And then there's the world map. Once I got into the simulation RPG part, I was shocked by how strong the protagonist was. But after progressing a bit, a monster with unbelievably high speed (if you haven't extreme-leveled, you'll definitely be pursued) and the defense of a leather shield (taking only 1-3 damage from physical attacks) was moving across the map one tile at a time, which was very, very terrifying... Even with Gaiden, the first time I played, I only reached the Liberation Army's hideout and decided to start over from the beginning. It seems there was a technique called the villager loop, so I thought I should change the villagers' class to mercenary and restarted. My save data before restarting, it seems I picked up the Angel Ring, this guy. Turns out I needed the super, super valuable, broken item, the Angel Ring, more than the villager loop!
