I think you all lack imagination. FC can be easily done in 12 episodes. SC in 26. CS1 seems very doable in 12 episodes too.
I mean, you could definitely do the main plots in smaller episode counts (not CS1, though. It's even longer than SC).
But what's the point?
The appeal of Trails isn't just the main plot, but all of the character development, the world building, the supporting cast, the environments, and so much more.
A 12 episode version of FC would probably be a decent adaptation of that game's main plot, but it would feel soulless. You wouldn't really get time to care about any of the characters aside from Estelle or Joshua, you wouldn't really be able to explore Liberl in any meaningful way, and if you hadn't already played the game you'd probably just look at the show and ask "is that it?".
Obviously an anime can't bring the world to life in the same way as the games do, but if an anime adaptation wasn't going to even try and just focus on being a rushed version of the critical path, then I'm not sure what the point is.
