Still Fire Emblem by a long shot. It was one of the least exciting things to see in the Direct because my mind was made up so long ago. FE is top-priority Nintendo for me, and Super Mario Maker 2 (which counts as first half, just barely) is the only reason it wasn't my most anticipated game for all of 2019 overall. The two are far too close together for comfort, and I am actually paring down my purchases as far as I reasonably can in order to make room for them.
Today's showings cemented that I'll be picking up Link's Awakening, Luigi's Mansion, and probably Astral Chain. On the PC front, I've already been in Early Access for ages for important 1.0 releases on the horizon like Oxygen Not Included, so the major event will be Warcraft III Reforged.
Borderlands 3 can wait a few years to be DLC-complete and on Steam. Pokémon is always filed under "if I find the time" (which hasn't been the case since B/W).
