Correct on all three. 29 is specifically Yakuza Zero.

Oh yeah, I should've seen that it was Zero. You wrote prequel.

Correct

Yakuza 0
(Change YoY: NEW!)

The second of four new games in my top 50 this year, Yakuza 0 essentially made me regret ignoring the series in the past as it instantly became one of my all time favourite open world games. How can I not just love a game that can somehow balance some absolutely ridiculously silly sidequests about an in-training dominatrix, running a hostess club or helping a fictional versions of Michael Jackson and Steven Spielberg film this world's version of Thriller, with a deathly serious main storyline where many characters end up dying in horribly gruesome ways while others have to suffer and struggle through constant adversity and opposition. 

It's an absolutely marvelous game. The world isn't as massive as most other open worlds these days, but it is infinitely more interesting and vibrant thanks to the game's genius design. As far as I'm concerned, you can keep your bland wastelands and oversized sandboxes. Sotenbori and Kamurocho are better than almost any other open world ever created.

Metroid Fusion

• GameBoy Advance
• 2002
• Action
• Nintendo R&D1/Nintendo

I'm still kicking myself about the fact that I missed 'Metroid Fusion' during the time the GameBoy Advance was the prominent Nintendo handheld. As it turned out, it was the best game in the franchise and the best original game on the system. It even happened to be one of the best handheld games ever. If only I knew sooner, but I had mostly abandoned the handheld and consoles beforehand sadly.

Contrary to earlier games in the series, the game focuses more on the story progression and less on the exploration, though there's still enough exploring to do after the game opens up later on. The story is almost that of a survival horror game, and takes the series's example, the movie 'Alien', further than ever before. Famous series protagonist Samus is stranded on an abandoned space station after answering a distress call and finds a species of parasites have taken over all life. One of the parasites takes the shape of Samus herself after she was infected and needed to part with her famous suit.

This antagonist is named "SA-X", and is certainly one of the best antagonists in video-game history. It haunts you throughout the game, and an encounter, even though scripted in the story, is genuinely terrifying. All you want is flee and hide when it appears. The whole game is able to ooze that eerie atmosphere all-around, and had I played it when it came out, it would even have severely helped my perception of the GameBoy Advance system as a whole.

Skyrim was one of the games I had to try out on the Switch. I like big RPGs and Skyrim delivers. It has somewhat dated graphics and the fighting system actually is not that excellent. But the game is so big and allows you a great sense of freedom. Do whatever you like. And the game offers so much what you can possibly do. This is quite fun for hours and hours.
