Trails in the Sky, the first one. I bounced off the game not once, but twice. I liked the combat, but it felt like all I was doing was quests from the guild's notice board, so I quit. But then I kept seeing TitS (heh) on various "Best of" lists, so I was like "FINE. I'll try to push through one last time". And then it clicked and I pretty much marathoned the entire trilogy.
The first game is good, buuuut I still feel like it's the weakest in the Trilogy. Story-wise, you get to the good stuff way, way later in the game. Everything that comes before is world building. And it's good, too. You get to see how the world works, how different regions of Liberl (the country you're in) operate and you also get a small glimpse of Zemurian politics (Zemuria being the name of the continent Liberl is on). This also gets vastly expanded upon in the second game.
I'm glad I tried it, because the writing is great, the music is incredible and I really dig the combat. If anyone wants to try it, definitely do. Just know that the first game is a slow burn. Worry not, though. Once the plot starts picking up steam, it doesn't stop.
