An expansion, which also serves as a sequel to the original's events, taking place right before the true ending which also adds a lot of context to its events, while further exploring the nature of a learning AI which tries to understand human culture, history, and art.
Gameplay-wise, the puzzles can be brutally hard and fully expect you to be a master of the game's mechanics. Thankfully, the original's most undercooked elemt (record/play) is not used a lot, so your frustration will never be with the game's design, but with the smoothness of your own brain.
A near perfect expansion to a near perfect game.

Imagine Hunt Down the Freeman, but actually good.
This is probably the besat HL2 mod out there, boasting it's great level design and variety, well written story, charismatic characters, and improvements to base HL2 formula, and all this while being as lore friendly as possible for such an ambitious project.
You play as Bad Cop/3650's clone afyer the events of EZ1 who is tasked by the Combine to search and capture Judith Mossman, while being granted freedom of thought just for this mission, which separates the MC from all the other Combine soldiers. Which means, he can talk. Which in itself means, that now we're playing as a Build Engine era protagonist, but this time in HL2 setting.
Surprisingly enough, the idea actually works, because the 3650 is extremely fun to listen to and play as. A lot of character has been put in all of his interactions, as well as weapon animations. The story brings in a lot of unique twists which I won't spoil. I will only say that it is truly a by fans for fans project, which means it's highly recommended to play thorugh at least HL1 with all the expansions, HL2 with both episodes, and at least Portal 1 prior to going into EZ2. And also, make sure to bring Wilson along with you :)
As far as gameplay goes, it seems the devs were playing through HL2 and were taking notes about everything they didn't like, because basiclly all of mine personal issues with it are fixed here. A lot of surprises with returning foes happen, as well as brought back remotely activating explosives from HL1. The expansions are so big that calling this mod Half-Life 2: Opposing Force doesn't feel like stretch at all.
And what's the most baffling about this project is that it's absolutely FREE.
TL;DR It's good, please play it.

terrible ideas at every corner. worst fusion system I've seen in a megaten game so far, mid plot, OK characters, dogshit dungeons, and a pointlessly convoluted but at the same time illogical and stupid combat system. if not for the word "persona" in the title this would be forgotten and abandoned but people still like to pretend that it's any good because they like the later entries.
but on the good side, the PS1 OST is pretty dope, sounds from both demons and characters are very cute and charming, and the story has some value. either way you'll probably get a way better experience if you read the manga adaptation as doesn't have skippable characters
oh, and snow queen quest is completely skippable. it's just a side story with no large impact on the main plot. you play it if you somehow want more of this ass gameplay after clearing SEBEC

Chipper & Sons Lumber Co is the game most people know about as a game which was criticised for it's art style and made the creator so mad, that he used the said criticism to later create the most popular horror game of it's decade that needs no introduction. But disregarding this criticism, is Chipper any good on it's own?
Sadly, it's not. The game is essentially a grinding simulator, with no end goal in sight. You are required to build structures of varying uses, which themselves require the more and more bloated amouts of resources. While there is automatisation possible, the said auto production structures usually also require bloated resources, which creates a hellish cycle of constantly grinding resources to increase the production rate of the same resources, only to find out that the new unlocked blueprints are bloated even more. The process never changes, you do the same things throughout the entire playthrough.
What doesn't help is that half of the resources you need to progress rely on random chance of dropping, sometimes only dropping from talking to the same NPC in 1 minute intervals. And even adding to the pain of it, the map never actually becomes bigger: you just get more lots to build structures/grow trees, with the rest of the playable area staying completely static from the very start.
The only saving grace the game has is the writing. Scott Cawthon is good at making witty dialogue with dark humor inserted from time to time, even going as far as hinting at Chipper being some sort of murdering psychopath, which is played for laughs. No, I'm not going to write a theory about it, since it's just Scott's way of adding comic relief to the game. I liked the writing so much, that it made me kind of excited to play FNaF World at some point in the future.
Is it worth playing? Well, it's worth at least trying out. I only completed the game because I'm planning to play a fan-made sequel (Tyke & Sons Lumber Co.) in the future.

Since I played it for the first time ever in 2022, when I'm already 20 y/o, I failed to really see this game as anything more than a history piece. It definitely has an appeal and is definitely a game which used to be someone's childhood, but from an outsider's perspective, I can't call it anything more than just OK. And as I noticed from the other reviews, people only ever rate it highly because they grew up with it and not because it has some phenomenal design in it. I don't regret my time with it because I at least finally learned what is this Pokemon thing about and why it stays popular even today.

NFS Underground is a blueprint for it's sequel and the single most important game in the series, which set the direction the series would mostly be going in for the next 20 years.
However, on it's own this game is broken, repetitive slog, which forces the player through repeating tracks over and over again while also having the opponents cheat their way to victory no matter what difficulty you pick. Each of the player's wins feels like luck since most of the time the reason why it happened is because the rubberbanding AI wasn't as broken as it usually is, the game's hyper realistic collision physics haven't flipped his car over on a straight road for no reason, or the traffic car hasn't spawned right behind a blind turn, sending the player's riced Honda Civic spinning 360 degrees and flying 3 meters into the air.
Do I recommend playing this game? Eh, purely for historic value. It looks really good for the time, the car selection is overall solid, and the modding options can look cool.
The music also has a silly childish charm to it, looking at it in the retrospect. Since it usually forces itself to be cool so hard that it turnes to being cringey, which in itself provides unintentional comedic value, making it great, albeit again not in a way it was originally intended.
