I'd have to disagree with the point about original Xbox being considered a success as it lost a lot of money for Microsoft. I don't consider it a success by any means. The PS3 may be somewhat more successful, but I'd say it's not doing much good for the PS brand, if not hurting it.
For the time being I'd say it's the strongest brand, but give it two years and the strongest brand will be Wii. A lot of it has to do with what kids grow up with, and a lot of kids have Wiis.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
