Video games that let you play other video games, inside the game (gameception??)

The Original Animal Crossing allowed you to play NES games.
Metroid: Zero Mission allowed you to play a port of NEStroid.
If you find the secret area in Celeste, you can play Celeste Classic.
Puyo Puyo Box contained ports of the original Puyo Puyo and Puyo Puyo Tsu for the Arcade/Genesis.
The Legend of Dark Witch Renovation allows you to change the style of the gsme after unlocking the old style which perfectly replicates the Original 2014 experience. this is due to both games utilizing the same engine as each other.

It's been a while, but I'm pretty sure that Always Sometimes Monsters had an arcade and you were required to play a game to pass a story sequence.

Hypnospace Outlaw also has the Enforcer minigame.
(I fucking love Hypnospace Outlaw and I can't wait for Dreamsettler).

This is something that will never come back. When they discovered they could sell these games back to you for 10 bucks a month it was all over.

In Castlevania - Dracula X Chronicles on PSP you could unlock the original Rondo of Blood, and Symphony of the Night by finding them in the game as pick-ups.

I always thought this was a really neat way of unlocking them because it kinda looks like the character is picking up the actual game boxes.

I love the idea of the Belmont family gathering around the TV while Richter pops in this new game he found in the dungeons.

The Dreamcast game Kita e: White Illumination has a hidden shoot'em up called Guardian Wing.

 

[Bomberman]

Ratchet and Clank Going Commando I think has a ship based game.

Up Your Arsenal has you collect game cartridges to play 2.5D platform action segments.

 

[partymembervii]

all or most of the newer wolfenstein games have the classic version somewhere in the game, and i know ffxv has a playable arcade cabinet in there. .hack might be the most famous example of playing a game within a game

The Shenmue games were notorious for this, and really well implemented.

Danganronpa 2’s second chapter has you investigate a murder by playing a video game and learning about it

 

[Xdqwerty]

Dunno if it counts but in DK64 you have to play the arcade DK game as part of a mission

 

[Boo Man]

Started playing Metal Saga today and first thing i noticed was an arcade machine in a building where you can play a mini game called Crossfire
it was fun but i spent all my money without realizing

you can even download the game (on a downloaded game) and rip music from the duke box

 

[Kovlak]

The og Dying Light has a DLC called Hellraid that is a arcade game acessible in-game. It was supposed to be a full blown game but was repurposed as a game within a game.

Observer System Redux also has a puzzle game, similar to Rapunzel in Catherine.

Not sure it counts, but Action 52 had fucking Pong in it.

Un GTA Sa un CJ's house you can play a simple games like galaga clone or others and in the arcade machines in some places
In Alice madness returns if you buy the DLC the game let you play American's McGee Alice (the first game)
Yummy Nikki have a little game Nasu, tries toa little red character catching eggplants from the sky
And....
A crazy guy did a Doom mod that's possible play Doom in Doom
Crazy, right?

 

[Fietto!]

In Devil Summoner: Soul Hackers (Saturn/3ds)
When negotiating demons like Mokoi or Jack Frost, there’s a chance to be offered to play a text minigame.
Apparently there’s two, I only remember the one I played. It’s a boat game where you dodge stuff, with the Micom theme from the original megami tensei as the bgm.

Now for a less niche example. You can fight SoR2 bosses in SoR4.

One of the coins of Donkey Kong 64 requires you to play the OG Donkey Kong
Guess Billy Mitchell will never see said coin
