Somehow this is not how games copyright works outside tetris company.
It totally does work that way outside Tetris. The difference is that most games these days are far more complex and it's far easier to take the basic idea and create something that, while the core gameplay is the same, fundamentally has a different look and feel to it.
Or, alternatively you get games where the concept isn't registered to anyone, so clones are a free-for-all (as is seen with LoL and all the other DotA clones), or where the company which came up with the idea is a fairly small independent venture without the financial ability to sustain a major lawsuit (as is the case for most of the games that Zynga has shamelessly ripped off).
Tetris sits in a fairly unique niche of being one of the few simplistic old-school games that is still being held as intellectual property and is being monetised. Most other games out there are complex enough to allow side-stepping, or are no longer being claimed as IP and are therefore not subject to copyright complaints. And most of the existing lawsuits in this area are from decades ago, where the legal issues around software copyright and software patents weren't so heavily in favour of the original creators.
Regardless of stuff said in this thread, the overlying fact is that the court, what with all its lawyers and judges and whatnot, decided that this is
how copyright law works in the US, and until that decision gets overturned I really don't see how a programmer from Poland (who seems to have a penchant for making clones of existing games, and therefore can be said to have considerable bias) can claim to understand the US copyright and surrounding legal system better.
