Okay. List makes little sense to me personally.
1. N64
2. PlayStation
3. DreamCast
4. 3DS
5. PlayStation 3
6. Wii
7. DS
8. GameCube
9. XBox
10. WiiU
Never played PS2 or XBox 360 so swapped those with 3DS and WiiU since those have also been released in the last 20 years. Especially the former has already been better to me than whole lifetimes of other systems. Of course, if this list were all-time, the NES, SNES and GameBoy at least would shake things up.
