What is the best gaming consol for video games by technial stand point

Well, that would depend. The Nintendo Wii is great for families, as the games focus on motion sensory. The graphics are not the best out there (they seem to equal the graphical capabilities of the original Xbox), but the motion control is very fluid and Nintendo has been praised for that, although the games may not be amusing for experienced gamers. The Xbox 360, the sequel to the original Xbox, has the best graphics out of all the systems, but some of the games may not be appropriate for the younger audience. The repertoire consists of mostly first-person/third-person shooters (FPS/TPS), but you can find some other genres as well.

If someone can add the PlayStation 3, that would be great.
(By the way, there is no "best console". This depends on what kind of games you like.)
