I always switch my game stations, But pick the Consol that has the best games for you. If you pick the wrong one, You'll easily get bored, and waste more time trying to plug in a new station. So pick one that feels best for you.
Ps3- free online gaming, certain titles such as God of War and Infamous series. Xbox-pay money for online gaming, kinect, certain titles such as Halo series, minecraft. Wii-have to move around alot Call of Duty not really fun due to moving around a lot, certain titles such as super smash brothers and other Nintendo games. I hope this helps! (I have had all three since they came out and I choose ps3.)
