Basically a synonym of trope, but without the negative connotation.
Ciro Santilli used to play video games when he was young. But after he reached 18 he got bored of them.
The problem is that no matter how you look at, the how to become famous in the real world game is just always more interesting and fulfilling.
Therefore adult Ciro enjoys only the following types of video game content in video form, so that other people waste their lives playing the games while you only see the highlights:
- speedrunning, including:
- tool-assisted speedrun, Ciro's favorite by far
- real-time attack speedrun
- meta breaking glitches, including in speedrunning and on PvP-games.
- Magic: The Gathering
- Video game reviews
The aspect Ciro enjoys about non-PvP games is atmosphere. Not as conveyed by useless story telling, but as conveyed by music and graphics, and the context deep idea. Legend of Zelda and Metroid come to mind.
And too many games commit the sins of dependency of dexterity, no save states, how do I skip this boring part, or jump straight to the beautiful one?
Another important point is; the perfect video game is an infinitely hard one.
It also doesn't help if you are already typing on a computer all day long on your job. Hands get tired. Eyes have an infinite capacity to consume useless YouTube videos however. Medically proved.
As a result, Ciro just watches videos about video games. Notably games he played when he was a teenager and already understand the rules for.
And things got even worse as after Ciro Santilli's Open Source Enlightenment, and he started to feel bad about playing any game that is not open source.

. He would get really mad because he could not finish those insanely hard games. Desperate, his parents would have to call older kids from the neighbourhood to help out. Pro tip from the future: the classic controller would almost always have been a more efficient controller. Maybe this kind of crap shapes one's future?Supercut of Doug S02E13 "Doug's Lost Weekend" (1992)
Source. Ciro Santilli used to watch Doug as kid. Of all the episodes, only this one stuck to his mind as an adult. It really drove the point home. The pain and joy of being addicted to anything really. Thankfully wheneve Ciro got addicted to a video game, he also quickly got tired of it. His last temporary addiction episode as of 2022 was Cataclysm DDA!
It is also so awesome how the episode pictures Dougs imagination while playing the video game, which is much more realistic than the actual crude graphics. The Nintendo hard reference is also clear.
Another great point of the episode is how good it is to play a single player video game taking turns with a friend on your side. Both people have to be fully engaged, and the game has to be hard. Perhaps those days are over now that everyone has their own computer and can each play together... and that is a huge shame. When playing on the couch with a friend, the one who is not playing can act as a copilot and thing more broadly as the other focuses on more specific details of execution. One is also reminded of pair programming.
Another great point is, partially when you are addicted, to play the video game at night until late, or very early in the morning. Ciro has fantastic memories of playing Zelda on the Nintendo 64 on Sunday mornings, or his emulation experiences from late weekend evenings at university: Video "Samba e Amor by Caetano Veloso (1975)".
The followup lucky hat segment is also amazing: doug.fandom.com/wiki/Doug%27s_Lucky_Hat
Looking back, the series is still extremely charming. It is interesting how Doug's best friend Skeeter Valentine is green. Ciro thought he was indian, but doug.fandom.com/wiki/Skeeter_Valentine says he's black.

Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01Ciro Santilli often sees all those genius who are much smarter than him making shitty forum/mailing list posts, they need to learn this:
- The apparently most important one liner error message must appear in the title, and fuller apparently relevant logs must appear on the body
- You must always give the version of the software that you are using as either a tag or git SHAThese are an important part of the minimal working example.
- For build errors, you must give your OS and compiler version and version of any relevant external library
