The Nintendo Wii is a cool system it can range from exercising to killing people all using motion detection. I have played my Wii numerous times. But this sense of overplaying the system was that I was all happy that I got it but then after a while I started to get bored with it and will lost interest. I mean it is fun to play with it but it will be like someone who has an Xbox after they completed Halo 2, there's no point any more. Also Wii is only good with games that are made only for motion capture. I would like to see Halo 3 become a Wii game.
The Playstation 3 is a little better as it has more variety of games and the games are more violent. Compared to the Wii you don't get as much exercise but you do get to kill more things and have more adventures. I like the Blu-Ray DVD player especially. Blu-Ray DVDs may cost more but it is actually better looking than the regular DVDs. The interface is just like the PSP one only with a little more features. I would like to see Gears Of War become a game for this.
Ahh The Xbox 360 my favorite system this has very good games with games like Halo 3, Gears of War, and Project Gotham this system has some of the best games for days ans days of fun and it has a low sense of overplaying so u can play for long periods of time without getting bored. Also most of these games have a very cool storylines and they are fun to just mess around with while playing.
This is what I think of these nextgen systems and their playability level.
