For me it would be...
1. Fire Emblem
2. Astral Chain
3. Devil May Cry 5
4. REmake 2
5. Dragon Quest XI S
Honorable mentions
Switcher 3 is easily in my top 5 for the year but unlike Dragin Quest, which had a considerable amount of new content to explore, Switcher 3 is the same amazing game that it was in 2015. Playing it on the go is def a highlight for me though so while I cannot put it in my top five for 2019, I can certainly spare a bit if extra praise for this amazing game.
Link's Awakening is another game that could easily make the list, but I just beat the original game again a year prior to playing the remake, which dialed back a bit of the spotlight for me.
