Starting with my personal Game of the Year for 2017, and continuing on with the rest of the top 10, these were my favorite games that I played for the first time this year! Originally 
posted on the Gamers with Jobs forums.
 
1. The Legend of Zelda: Breath of the Wild (Switch)
 - Bravely and brilliantly replaced the longstanding Zelda trope of "do a
 few large dungeons, get the Master Sword, do several more large 
dungeons" with a huge world that's really worth exploring. Exploring the
 wilderness and happening upon concealed shrines managed to re-evoke the
 feeling of discovery that I remember from playing the original NES 
Zelda as a kid!
2. Super Mario Odyssey (Switch) - Full of great 
surprises, beautiful art, fair challenges, and so many things to do.  An
 even better iteration on the gameplay, level design, and themes of past
 Mario 3D titles (Mario 64, Galaxy, 3D Land) than I might have thought 
possible.
3. SteamWorld Dig 2 (PC) - Rolled into this directly
 after finishing SteamWorld Dig 1 for the first time, which turned out 
to be an excellent way to approach it, with the NPC Dorothy from the 
first game turning PC and searching for Rusty, the first game's hero 
gone missing.  Solid digging gameplay with lots of fun character 
upgrades, both major and minor.
4. Blaster Master (2017) (Switch) - Blaster Master 
for the NES was one of my personal nostalgic favorites. A great update 
while still retaining the best parts of the original. Played through it 
twice, getting the fun surprise at the end of the second playthrough for
 100%-ing the game up through the boss.
5. Mario + Rabbids Kingdom Battle (Switch) - Great 
tactical strategy game, minimizing the impact of luck on the gameplay, 
and building on the foundation laid by X-Com by introducing lots of neat
 new gameplay mechanics.
6. PPKP (iOS) - A simple yet interesting 1-on-1 
brawler-type fighting game perfectly tailored to being played on a 
mobile phone.  Manages to make a deep and rewarding combat and upgrade 
system out of only two in-game "buttons".  
App Store link.
7. Mario Kart 8 Deluxe (Switch) - My favorite racing
 game in a long time. I actually enjoy watching others play this almost 
as much as I enjoy playing myself; while just observing, I notice all of
 the beautiful graphics happening in the environment around the race 
track, whereas when I'm actually playing I tend to tunnel vision in on 
the race itself.
8. Metroid: Samus Returns (3DS) - A very cool stride
 forward in 2D Metroid games with the counter-attack and 360-degree free
 aiming systems, even though I think I may still prefer the elegant 
simplicity of the original Super Metriod (SNES) gameplay.  Interesting 
to compare and contrast this Metroid 2 (Game Boy) remake with last 
year's indie take on the same, AM2R.
9. Cosmic Star Heroine (PC) - A 16-bit-style turn-based RPG in a sci-fi setting with an interesting new battle system. 
Steam link.
10. Fire Emblem Heroes (iOS) - A nicely simplified 
pocket implementation of the standard Fire Emblem gameplay.  I enjoyed 
it when it came out, although I did lose interest fairly soon after 
reaching the level cap of 40, despite the new content and events 
periodically being released.
Honorable Mentions: Puyo Puyo Tetris (Switch); Hollow Knight (PC); Snipperclips (Switch).

2016 (GOTY: Stardew Valley). 
2015 (GOTY: Super Mario Maker).
