Forgive my ignorance, but are Trails of Cold Steel and Trails in the Sky the same series? I see both names thrown around along with part 1 and part 2 and the games in general have been on my radar for a while, but I never know where to begin with them or how many games there's are.
Yes... same serie called The Legend of Heroes but it is a bit more complex :D
The series started with two games:
Dragon Slayer: The Legend of Heroes
Dragon Slayer: The Legend of Heroes II
After it started the trilogies:
Gagharv trilogy (the first trilogy)
The Legend of Heroes III: Shiroki Majo
The Legend of Heroes IV: Akai Shizuku
The Legend of Heroes V: Umi no Oriuta
Trails in the Sky (the second trilogy)
The Legend of Heroes VI: Sora no Kiseki
The Legend of Heroes VI: Sora no Kiseki SC
The Legend of Heroes VI: Sora no Kiseki the 3rd
A two game arc:
Trails – Crossbell arc
The Legend of Heroes VII: Zero no Kiseki
The Legend of Heroes VII: Ao no Kiseki
And finally the 4 last games:
Trails of Cold Steel
The Legend of Heroes VIII: Sen no Kiseki
The Legend of Heroes VIII: Sen no Kiseki II
The Legend of Heroes VIII: Sen no Kiseki III
The Legend of Heroes VIII: Sen no Kiseki IV
There are three spin-offs too.
