Haha You have no idea how much i almost dropped Trails in the Sky in the beginning because the game was boring and stuff. But somehow i insisted on this, and i really really glad i did back in 2014 like.
When the game actually clicks, the payoff is out of this world. The second half of the game is great, then you'll need Sky second chapter in your life, and Sky the third after that.
And i can't imagine someone playing Trails in the Sky the Third and not getting completely obsessed with this series. You'll have to go out of your way to play Zero/Ao no Kiseki, and you will have the need to play the Cold Steel games after that, trust me.
So yeah, i would say try to stick with it. The games are slow as fuck but there's no payoff as great. Flash forwarding 5 years after almost dropping the first Trails in the Sky multiple times, this is easily one of my favorite series ever.
Not saying the same will happen to you, but try to atleast reach the end of this game. If you're not completely hyped to play the second one in the exactly moment you finished the first, then yeah, this series is not for you.
