Favorite games, huh? Let's see...
The Portal series, the Half-Life Series (but mostly HL2, I only played the original Half-Life once and while it was a fun ride, I really prefer the focus on characters and story that 2 was able to have because of the advance in technology. That being said, I really adore Crowbar Collective's Black Mesa, especially its Xen!) Undertale and Deltarune, Disco Elysium, the Psychonauts games, To the Moon and its sequels, Omori, Inscryption, Celeste, Night In the Woods, Anodyne and Anodyne 2, The Talos Principle, Oneshot, and the very weird and SUPREMELY underrated visual novels
Milk Inside a Bag Of Milk Inside a Bag of Milk and
Milk Outside a Bag of Milk Outside a Bag of Milk!...I have a lot of favorites, and my taste in mechanics and genre is pretty all over the place. I mostly play games to get wrapped up in stories, but there are some exceptions where I also just enjoy how good the gameplay feels, like Celeste and Inscryption. I've noticed that I have a special love for games that use character's minds/dreams/memories as settings, To The Moon, Omori, and Psychonauts all take the concept in radically different directions and they're all games I adore.
If I had to pick one favorite game, it'd probably be Portal 2, because when I was younger it really changed my perception of what video games were like, what they could do, and just how
funny they could be, even if they looked "serious"!
Also, shoutout to this game! Holy crap I have never felt so seen by any piece of media before what the heck
