Honestly, TMS #FE is my GotY for last year, even though I put Steins;Gate 0 as my number one in the GotY 2016 thread. It was and is pretty close with those games though. I ended up loving TMS so much more than I thought I would and it didn't help that some elements of that game are in P5 (dungeon design a bit, aesthetics/style, the texting/messages mechanic, some of the battle system). That was bound to happen since both are SMT related.
I would also love a Switch port with a little new content and maybe slight QoL changes like possibility to skip some of the special attack animations since some of them can get old after seeing them and they take quite a bit of time to finish and faster load times. I think it deserves a second chance. I think Codename: S.T.E.A.M., also, got a bad rap and it's one of my favorite 3DS, but I don't think much could say it that they didn't do with speeding the turns up.
