As someone who played Undertale countless times, finished both major routes, and exhausted all dialogue in the game, Deltarune feels like Toby Fox saying "This is what you wanted, right?" and punching me in the gut.
On its own, Deltarune is an interesting experience with a complete arc - I went through a range of emotions by going in completely blind. As part of a larger narrative, Deltarune makes me feel like a conspiracy theorist - I've come back to think about it and its relationship to Undertale over and over again, and all it ever amounts to is Toriel and Asgore: Divorce Theory.

It's hard to define Chief and Cortana's relationship, but there's definitely something Freudian about it - Cortana was created from a flash clone of Doctor Catherine Halsey, who was also in charge of the SPARTAN-II program, taking on a distorted mother role to Spartans such as John-117.
Anyway, I had a lot of fun with Grifball and the Flood game mode of Halo 4 when I was 14.

I have played this video game over 15 times.

Has anyone ever thought about the troubling implications of Halo Mega Bloks?
It's worth acknowledging many childrens' toys are army-themed, and their positive portrayal and commodification is propaganda for a vague notion of an often undefined military. However, Halo is a series that has several traceable links to the actual United States Military, and Mega Bloks is a toy children's toy company, making Halo Mega Bloks something more: an army recruitment tool for young children and teens.
Anyway I think Halo Reach is a decent game.

A game that automatically discredits all modern portrayals of Shadow, in which he is a ruthless character that others dread interactions with - in his game, he is a confused, traumatised little man who is shown nothing but unconditional love from almost everyone that speaks to him.
Shadow the Hedgehog is a game with several branching narratives, tackling recurring themes of identity, patricide, and redemption through gay love. I don't know if that last one was intentional - though it is a fact that all sequences in which Shadow has several meaningful interactions with Sonic, and moves from dark to hero route, have canonical names such as "For Love's Sake" and "Under the Name of Love".
Shadow the Hedgehog also happens to not be a very good game, but it isn't offensively bad either. The controls can be slippery at times, but most of my personal frustration came from mission completion requirements. Each level has two or three missions to chose from, many of which require a specific number of well-hidden enemies to be defeated. There tend to be more of these in levels on pure hero or dark routes - if you're going through all routes to get the True Ending then I recommend those routes first, then work inwards towards neutral for an easier time as you near the end. This is a game that gets better the more you play, and the more you learn to effectively wrangle it's controls and requirements. The OST slaps.
In all honesty, this game is only worth playing if you have a high tolerance for kinda shitty game design and love Shadow (the character) very very much. Also I think Shadow is gay. 🏳️‍🌈🏳️‍🌈
