A lot of Nintendo consoles and games for these can be found on the sale. I think you should buy the one you had as a child or vice versa, the one you never had. If I were buying a console, I would choose the Nintendo DS because it's handheld and it doesn't need to be connected to other devices. DS Games
was my first video games I ever played, so I have an incredible fondness for it. The Wii is more newer than the GameCube and the DS. The Wii has motion control because it has an accelerometer and an optical sensor. So you should choose by what is more comfortable for you. You can buy games to all consoles, do not worry about that.
