The sole amount of time spent playing a game doesn't consider the parts of the game that didn't entertain or were even frustrating. I guess you can't just substract these "wasted" hours either because a 20 hour game without any frustrating parts is likely to entertain you more than a 30 hour game that includes 10 hours of frustration. It depends a lot on how much your free time playing games is worth to you in the first place. It may even be worth so much that you enjoy a five minute Solitair game a lot more than going through five minutes of just learning the controls of any other game, as an extreme example. The location of the bad game parts is also important as five minutes of frustation every now and then are less likely to decrease your entertainment than a bad two hour part in one go, especially if that were your only two hours of playtime that weekend.

No, it's impossible. Once a government starts to censor a certain type of illegal content, the censorship will soon expand to include every other type of illegal content as well (warez, hacking tools, bombing construction manuals, all porn sites without youth restrictions,) followed by content considered harmful (islamistic and nazi propaganda, governmental uncontrolled gambling, information about drugs) and sooner or later include every website the current government doesn't like for any reason whatsoever (discussing loopholes in law, sharing speed camera locations, oppositional opinions.) This will happen because "the government has to protect it's people by all means possible" and once new possibilities are clearly available, they have to be applied due to political pressure.

Of course, in Germany, censorship is actually unconstitutional. It's not a coincidence that it starts with childporn even though it probably only represents a very small fraction of all illegal websites. It's the one subject nobody can argue against without commiting political suicide. Nazi- and antisemite stuff will certainly follow next, opening the door for everything else.
...and that's still not the end. As the list grows bigger, the process will get automated and imperatively include every website providing comments that are not pre-moderated. The crawler will repeatedly find posts with links to goatse on Slashdot, stored at different imagehosts that will all be banned one after another until Slashdot will finally be banned directly. The endresult will be a whitelist. The question is not if but when. It took ten years to get this far; give it another ten and we will be there.

The fact that these kind of extensive cuts to people's right of 'freedom of speech' is currently happening all the world, for many unrelated different reasons no less, should be alarming.

I used to buy a $2000 high end gaming PC about every two years and played the first year on the highest possible settings and already hated the machine, when I had to turn a few things off during the second year. Now, I just buy a $500-$800 PC every 3-4 years and I still play at the highest possible settings most of the time. Two things changed:
1. I just concentrate on a good graphics card and buy everything else for cheap; onboard sound, $30 case, etc. (yes, it doesn't really work for GTA IV. It seems to be the first game that needs a high end CPU and I hope it will also be the last.)
2. Back in the time, I didn't consider a game to be running fast, when it wouldn't run at >100 FPS. Today, 40 FPS is good enough for me. I don't know how this perception excatly changed but I guess I just got older and can't really tell the difference anymore.

Amazon is kind of doing the opposite for years now - placing ads on torrent-sites and the like, where you can buy the same item from Amazon you are about to download for free. Therefore 'parody' is indeed the right term to use for this plugin.
