I can't make a top 5 per year, there are many years where I truthfully only liked two or three games, and other times I didn't even play more than three.
So I'd rather make an overall list, which goes like:
1. DOOM Eternal
2. DOOM 2016
3. Ys VIII
4. Fire Emblem: Three Houses
5. Zelda: Breath of the Wild
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
