ehh i might try FE if i have time
Awakening is the most new-to-the-franchise/beginner friendly, a lot of the components from the older games were removed to make it appeal to a more general audience.
Rekka no Ken (FE7, or just Fire Emblem here in the west) was recently released on Wii U VC, so you could try that as well.
FE7 being the first international title in the series.
I would recommend the other international titles as well: Sacred Stones, Path of Radiance, Radiant Dawn, and Shadow Dragon (which is a remake of the first FE game).
Although Shadow Dragon has a bad reputation among the FE fanbase (I don't know why though, I didn't have problems with it).
But those are going to be hard to get your hands on nowadays.
If you do decide to try FE, I must stress enough not to let your units die and not lean to heavily on the higher-level or promoted-class crutches that the game can give you.
Otherwise your time later in the game will be hell because you will either be short units or really imbalanced in terms of levels (unless you do an Easy run, in which you can probably pull it off).
Of course the former issue can be remedied if you pick up Awakening, due to the fact that it has "Casual" mode, wherein your units can be defeated but they don't die and can be used in the next battle. "Classic" on the other hand is death, if they are defeated they are gone.
Hope you enjoy it if you ever take the time to try it out.
