I have a PS3 and a Nintendo Wii. I love the Wii. You get to excercise and play on your console at the same time, it doesn't get much better than that. The PS3 is good but I need a better TV to play it on, a bigger flat screen would be good.
We have a PS2 but the Xbox is so powerful and has so much potential. The Wii looks interesting though. The excercise possibilities are great.
Right now... I must say xbox 360 is the best game system in term of games software but once amazing games come out for ps3...sony will dominate once again the console games industry
PC. The Wii is unique in the fact it's motion sensitive, but right now there are no solid games coming out. Nothing groundbreaking, just mostly generic movie based games. Once we see some Super Smash Brothers Brawl, Mario Kart and other IP's the system will be unstoppable. The Xbox 360 has a nice game collection but doesn't really change anything with gaming. It's just the same as the xbox except better graphics. The Ps3 has adopted a bit of motion sensing, but IMHO They just ripped off of Nintendo and added REAL TIME WEAPON CHANGE.
