legal – To what extent can one game legally resemble another?

Foreword: Everything related to the laws will always be in a gray area, because the outcome of the case ultimately comes from a handful of people.

Others have pointed out that the code and the assets of the game are under the copyright law and that the names of the products, companies, etc. they are under the law of registered trademarks.
However, although others have pointed out that you can not protect the mechanics of the game, this is not 100% true.

Let's look at the legal history of Tetris, a game often cloned by new game developers.

In mid-2006 and at the end of 1997, the TTC legal counsel sent cease and desist letters to the websites based on Tetris-type games that infringe the trademark, commercial image and / or copyright of "Tetris" , and / or "copyright". Around 2009, TTC and Tetris Holding LLC filed legal actions against BioSocia, Inc. because the game "Blockles" of BioSocia infringed the property rights of TTC and Tetris Holding LLC. On September 10, 2009, the legal case against BioSocia was resolved, and BioSocia agreed to stop making the game "Blockles" available to the public. In May 2010, TTC's legal counsel sent cease and desist letters to Google insisting that 35 Tetris clones be removed from the Android Market. A judge of the US District Court UU It ruled in June 2012 that the clone Tetris "Mino" of Xio Interactive infringed the copyright of the Tetris Company by replicating elements such as the dimensions of the playing field and the shapes of the blocks.

Mino vs Tetris

Tetris and Mino

So, the mechanical games are copyrighted? The answer, as with many legal issues, is perhaps.

readability: to what extent is the blank text on a medium to light gray background objectively a bad practice?

I made the mistake of openly criticizing a web page because they asked me for an opinion. I ruled negatively. To what extent is the designer guilty of my unfavorable criticism?

Legibility judged objectively?

Here intrinsic and external factors intervene, such as monitors and eyes.

The small text, from 8 to 10px, white, in a solid tone of gray, which is somewhere between 10 and 35%, still made me fall a "star" … probably because the LCD helped me. The viewing angle of the screen, the density of pixels, maybe even the reflection of the screen could have influenced me. However, am I to blame or is this supposed to be avoided?

Since I have a slight astigmatism, I should not appreciate small sources that are too thin or light. But actually I use this configuration at this time for my desktop environment, with supbixel processing enabled as a necessity to render the font correctly, it is very thin. I'm not blind

Is it sustainable that one should not have to weigh such external factors, if one adheres to good practices, as a greater contrast between the text and the fund?

There was also no real need to choose such a clear gray. What finally gave me the impression of being careless, while the author could have tried to keep things warm and cozy with his choice of colors.

Relevance issues

The thing is that the user is not reading a poem with this configuration. I'm talking about the menu items that will only be read really until the user learns instinctively in the third word of the row.

Personally, I think readability is important. But good practices are not rules and I can not penalize the author because he violated Article X. Is this still somehow objectively A misstep from a UX perspective or is it rather that I was prone to simply "finding fault" subjectively, frustrated by not being able to read some words at a glance? To what extent is the white text on a light gray background objectively a bad practice?

Bonus question in the same line:

This menu was also hidden unnecessarily from the view, until it was invoked by a click. This superfluity made me fall another star, since it gets in the way of efficient interaction. Except, it's just an additional click. However, making a furore in the dynamics for the sake of having dynamics can be done without getting in the way.

The same question. Did I hold a valid resentment? Should the author get it or rather be offended?
