My Recommendations
My personal recommendations are that you should buy a type of XBox 360 they have very good memory space and they can play a variety of games both motion and regular gaming. Now i also recommend that you have more than one console in the house hold like I have an XBox 360 Kinect Ready and a Nintendo Wii for the more options of gaming.
Now it also depends on what type fo game's that you like so if you like the classical Donkey Kong, Mario, and Metriod game's than you need to get the Nintendo Wii because it plays those old game's and the new game's also. Now if you are the one who will play a lot of shooter's and RPG's than you will want the XBox because of graphics, memory, and hardrive.
