Online games are always unpredictable thus stay fun. I've poured nearly 2700 hours of driving time in GT Sport in 740 days. That's about the same pace, 3.5 hours a day, about 14 online races a day on average. Seems a lot, and it is, but I do everything that needs doing in the down time while the game counts down to the next race. 3 races an hour, 11 minute race, 9 minute wait. 2 tvs in the living room, one dedicated to gt sport. I play with the sound really low, no voice chat, just race while watching tv. Some people can't stop touching their phone, I'm racing instead.

Time to boot up the game, off to Bathurst while working out in between the races.

I can't pick one.

A three way tie between LoZ:A Link Between Worlds, Batman: Arkham City, and Super Mario Galaxy 2

very closely followed by: Fire Emblem Three Houses, Xenoblade Chronicles 2, Super Mario Odyssey

Persona 5.

100% agree on VR. It's crazy just how immersive it is.  It makes you want more games to support it. RE7 and Skyrim are pretty nuts in VR.

Though, I'd have to give it to Astro Bots. It was the first VR game I played and shows how great a platformer can be when you feel like you're in that world. It's also one of the more fleshed out games, where some of them seem more like extended tech demos.

On a side note, I hope Sony eventually has London Studio make a full fledged London Heist game.

Rocket League is a very cathartic game. I put it on whenever I need to have something to do with my hands but don't want to think much. So I put on music or my everlasting youtube queue and play away. I should mention that about half of those 4000h I played alone either in training or against bots.

I love playing with friends casually or fully concentrated in ranked. I like the thousands of customization items and since they introduced the Rocket Pass I'm compelled to play even more. I'm also very much engrossed in the esports side.

Rocket League basically completes my person. It gives me friendly social interaction without pressure, childish delight when getting new items, catharsis when just trying to relax and heart pumping entertainment when watching high level sports. At this point the game has become an integral part of my life and it's great because it is so simple, yet so fulfilling.

note: While I'm writing this comment I'm ingame in training with my watermelon themed car and I'm having the time of my life.

Breath of the Wild clearly.

I've played many games this decade but clearly this one hits different. A masterpiece and instantly legendary, it's rare games that you play and you just know it will be iconic later on.

That's somewhat similar to me and Overwatch. It's my go-to online game and just default diversion if I want to play a game but don't want to get too wrapped up in learning a new game or only want to play for 30 mins or something. I can kick back and relax by playing against bots, play with friends in a more casual setting, mess around with the Arcade Mode options, or buckle down and go full-blown competitive, which is usually a lot more stressful but also more thrilling.

Rocket League is also becoming a sort of secondary default option for online gaming for me, especially when playing with my cousin who doesn't have Overwatch and isn't too keen on it but loves Rocket League. Only problem is I'm still not so great at RL heh. 

Breath of the Wild, easily.

Runners up are Dragon Quest XI S, Fire Emblem: Three Houses and Ni no Kuni.
