Missing categories is more interesting to me than disputes over which game is truly the best.

Best RPG? Perhaps 0ad
Best Sim game? Perhaps Micropolis
Best Tower Defense game? Perhaps CreepTD
Best Racing game? Perhaps TORCS

"Best" is sufficiently subjective that I think you ought to add an Honorable Mention list for those games not the "best" but competitive.

I do appreciate the list and read it every time it comes out. I never fail to find something I'm interested in trying. Thanks for your work.

by Jojo Yee on 31. May 2013 - 6:58  (108173)

Good suggestions CorporalPunishment. TORCS has been reviewed by editor George J. and is now added to this list as well. Other suggested games will be looked into.

by Jojo Yee on 31. May 2013 - 7:03  (108174)

Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs:

* Graphical user interface (Qt-based).
* Faster than VLC and ffmpeg/avconv.
* Records the entire screen or part of it, or records OpenGL applications directly (similar to Fraps on Windows).
* Synchronizes audio and video properly (a common issue with VLC and ffmpeg/avconv).
* Reduces the video frame rate if your computer is too slow (rather than using up all your RAM like VLC does).
* Fully multithreaded: small delays in any of the components will never block the other components, resulting is smoother video and better performance on computers with multiple processors.
* Pause and resume recording at any time (either by clicking a button or by pressing a hotkey).
* Shows statistics during recording (file size, bit rate, total recording time, actual frame rate, ...).
* Can show a preview during recording, so you don't waste time recording something only to figure out afterwards that some setting was wrong.
* Uses libav/ffmpeg libraries for encoding, so it supports many different codecs and file formats (adding more is trivial).
* Sensible default settings: no need to change anything if you don't want to.
* Tooltips for almost everything: no need to read the documentation to find out what something does.
