The series has a lot of great games IMHO. I kinda like the classics a bit more as a whole, but I also love Three Houses. I'd recommend Sacred Stones and Path of Radiance as those two are my personal faves, but you can't go too wrong with most of the games (besides maybe Fates, but that's mostly just my personal taste).
The games are as follows:
| # | Name | System(s) | Saga (and where in Saga) |
|---|---|---|---|
| 1 | Dark Dragon and the Sword of Light / Shadow Dragon and the Blade of Light | Famicom | Archanean (Beginning) |
| 2 | Gaiden | Famicom | Archanean (a Side Story 1 year after the 1st game) |
| 3 | Mystery of the Emblem | Super Famicom | Book 1: Remake of the 1st game |
