Fire Emblem or at least the ones I've played are more strategy focused than FFTA. I mostly have played the older ones but in those there is a limited amount of chapters in the game and you can't get exo anywhere else. Characters also die permanently so either plan carefully, restart the map or be willing to lose a unit, the game gives you plenty but they're all unique and have some degree of personality. Newer ones are much more forgiving in that they let you grind for XP and you can turn off permadeath. I understand the change cause the original concept is a hard sell but I liked having to plan my shit carefully. Awakening is a good newer one to start with and the first American released GBA one is the most accessible in the more classic style. You can kinda go from there. There are some great earlier ones on the SNES that you can get translated roms for easily enough.
