This particular example was a compromise on keeping game-recs. The alternative is to remove them altogether.
At one point, they were wiki'd, because they became an opinionated list rather than anything really useful that you can't find anywhere else.
If you really want to see the genesis of the question and the solutions, take a look at the following questions:
Has [system-recommendation] grown too big for its britches?
Are game recommendation questions on topic?
As one of the vocal mods on that thread, mxyzplk is very stringent on keeping people on point in that regard.
After some correspondence in the comments, I understand where you are coming from a bit more. I can't speak to everyone, but I did upvote the AW comment, and did not upvote yours, so I can speak to my reasoning.
The points in question from the question were
- Rules Light
- Not d20
- Flexible and Fluid combat system
- Modern setting without anything weird.
First, to get to your supposition that the games are the same:
Apocalypse World and Cyberpunk are indications of two different eras in game design. That rough middle patch between Roll-playing and role-playing, and the new Story game renaissance. Based on that alone, from my experience playing, they are totally different creatures.
In terms of tone, Cyberpunk is more of restricted by its audience, and the fact that it was very popular commercially at one time. So it's edge is dulled, just like Shadowrun. It hints at an edge, but doesn't really have it.
In terms of interaction between the players and with the environment, in Cyberpunk most of it is artificial and at the whim of the GM. In AW, the whole game is exactly about this point.
To move on to the requirements for the question:
Cyberpunk is not rules-light, and doesn't have a flexible and fluid combat system.
This is my opinion, and informs my decision to upvote/downvote/novote. It is where RPG.SE is different from SO and some other quantitative sites (though it comes up there too, which is the reason for the Code Review SE). Unless you're talking about RAW, a lot of things to deal with game philosophies and views are based on opinion and experience. And that's ok IMO.
What we end up with in regards to upvotes and downvotes in those cases is a cross section of experiences and views on systems- which is what these questions are in the end for. I'd never downvote an opinion. My only reason for a downvote on this type of question are if you violate a rule. Even then, I rare use my downvotes, preferring instead to comment. On questions like this, because I disagree with the experience rule being an absolute ruler, I rarely downvote for not including experience, but instead upvote for it, using the downvote only in the case where someone lists a game and does nothing else.
I hope that helps. As I said in the comments on another question, your rep indicates that a good group of people here think that your contributions are valuable. Just don't take downvotes personally- that has helped me a lot.
