| Miyamotoo said: "December was a big month for Nintendo. Seven of the top 20 games are exclusive to Nintendo systems, which is significantly more than any other publisher. Every Nintendo game is benefiting from the Switch’s success. Mario Kart 8, for example, finished 2018 as the second best-selling racer ever behind only Mario Kart Wii. Nintendo generated more revenue than any other game publisher for the first time since 2009. That doesn’t include in-game spending, though." https://venturebeat.com/2019/01/22/december-2018-npd-smash-bros-beats-spider-man-in-exclusives-battle/ |
Yeah, December was such an impressive feat for Nintendo. Also for Mario Kart 8 (Switch + Wii U) to be NA's 2nd best selling racer ever. After declining 44% from March 22, 2018 to December 25, 2018, my NTDOY stocks are now rising again. 
Over all, Nintendo and PlayStation exclusives did great this year in NA with even 3 ending in top 10.
Top 10 best-selling games in 2018 in NA:
1. Red Dead Redemption 2 (PS4, XB1)
2. Call of Duty: Black Ops IIII (PS4, XB1)
3. NBA 2K19 (PS4, XB1, Switch, PC)
4. Madden NFL 19 (PS4, XB1)
5. Super Smash Bros. Ultimate (Switch)
6. Marvel's Spider-Man (PS4)
7. Far Cry 5 (PS4, XB1, PC)
8. God of War 2018 (PS4)
9. Monster Hunter: World (PS4, XB1, PC)
10. Assassin's Creed: Odyssey (PS4, XB1, PC)
