So many have had lasting impacts on me for different reasons. Recently OneShot was an unforgetable experience. If we go by play time Final Fantasy XIV would take the cake easily, and I love that game to bits. Platinum games consistently makes some of the best gameplay I've ever experienced, with both Vanquish and Bayonetta being stand out titles. XCom 2 scratches a strategy itch nothing else can for me. The whole Disgaea series manages to win me over with its charm, but especially the first. JRPGs like Chrono Trigger, Radiant Historia, and Lost Odyssey constantly remind me why I absolutely adore the genre. The Mass Effect series was one of the first to get me to think incredibly deeply about narratives and choices. The Legend of Zelda in all its forms manages to distill pure nostalgia and even if I don't follow it much these days it still holds a special place in my heart. The Sly Cooper, Jak & Daxter, and Ratchet & Clank series all lit my imagination and got me to love stylized worlds and personable characters. Satisfactory and Factorio manage to engage the logical fun side of my brain like nothing else. Shadow of the Colossus is such a somber masterpiece that speaks so much to me with so few words. And I always find myself getting pulled inexorably back to almost a few rhythm games, mostly DDR/Stepmania, with shocking regularity. Mice Tea was an incredibly special and well written experience for personal reasons, hehe.

In Stars and Time was also one I played recently that captivated me with everything that it offered, from incredible writing, a riveting plot, amazing lgbtq+ representation that let me feel seen, and themes that resonated with some of the most personal struggles I've ever had. I would almost want to say that would be it, but...

I think in the end I have to say the Kingdom Hearts series. Kingdom Hearts 2 in particular, if I had to pick one. It was a formative memory, and yeah it's very silly, immature, and self-indulgent at times. It is almost amongst the most convoluted of anything I have ever experienced. But it lit my imagination in ways that persist within me even 20 years later, and still fills the way I view the world and my connections with others in so much color. I don't think I'd be the girl I am today without it, hehe~

Soulsgames rank high, but it's been a while. Fire Emblem very very high up, I love turn-based strategy generally and I love the worlds and characters FE creates. Especially Radiant Dawn has been a refuge for most of my childhood and gave me my chosen name, Mia. I really liked both Subnautica games and played them to 100% completion, a shame the devs got fucked over. I really loved signalis even tho horror games kill me, but I still plan to 100% it as well. Big fan of factory games, especially Satisfactory that I played since the first open Beta like 8 years ago -- played every major update until 1.0 last year. Minecraft is an all time favorite that I must have played for thousands of hours, through various mod packs and dozens of servers. I love love love jrpgs like dragon quest or tales-of games but each of them takes a hundred hours or more to complete so my backlog there is centuries long...
There are also a lot of games that had a big amount of influence on me? I fear it may sound stupid but doki doki literature club.. I played it completely blind and it changed how I see fiction, and what fiction can be (and I was too down on Monika for a long while). "Your reality" to this day activates neurons in me. Divinity games were a savior in downtimes between semesters and gave me an appreciation for these types of RPGs that then later blew up with baldurs gate. Mario games -- and many first party nintendo games -- for me always have been a beacon of quality, showing me that no, releasing your games with lots of bugs does not have to be the norm. I don't remember a single bug I ever found in a nintendo game like that and I wish the entire game industry would hurry up and collapse and rebuild with proper quality standards.

... I really like games I guess. I mean I did lead a few game projects myself so I have strong opinions there too.
