Nintendo primarily;

1. Sony PlayStation
2. SEGA Dreamcast
3. Sony PlayStation 3
4. Philips G7000 (Magnavox Odyssey2)
5. Atari 2600

Even though I have it, I'm not that fond of the Mega Drive. I don't have that many games for it though, and haven't played them that much even though I like some of those I do have, so the system is probably better than I give it credit for. The original XBox is cool, and played it quite a bit, but it's games aren't very unique as I can play most of those I liked on PC. In that sense I like those two 2nd Gen consoles better, because while simple, they have some fun unique games.

If PC is included though, that would easily be #1, knocking off the Atari.

Alright! I wish I owned more non-Nintendo systems than I currently have. I like the Vita better than the Xbox.

1. Xbox 360 (which would probably still win WITH my favorite company!)
2. Playstation 2
3. Playstation 3
4. Dreamcast
5. Playstation

for the record, even though Nintendo is my favorite company, a lot of consoles from their competition would beat their consoles. As much as I loved the 'Cube, Wii, and N64, they weren't the best on the market during their generation in my opinion.

Playstation fan!

1. Xbox 360
2. Wii
3. Nintendo 3DS
4. Gameboy Advanced
5. Gameboy

1. PS3
2. PS4
3. XBOX
4. PS1
5. Dreamcast

PlayStation is preferred consoles

1. SNES
2. NES
3. Gamecube
4. Genesis
5. Dreamcast

1. PS3
2. PS2
3. NGC
4. XB1
5. PS1

Number one could change depending on how well MS handle the XB1. I'm loving it right now.

I'm biased when it comes to SEGA, I absolutely adored the Mega Drive and the Dreamcast, they played a big part in my childhood.

1. PSP
2. PS1
3. Saturn
4. Genesis
5. PS2

No Nintendo consoles in my list.

1. Master System
2. PS1
3. Xbox
4. Dreamcast
5. Pong

The Master System wins by a landslide, so many excellent games.

And yes, Pong is still better than most games today.

1-PS3
2-PS2
3-Dreamcast
4-Megadrive
5-Um (literally cannot think of something to add here)

*I am a Nintendo fan in case you were wondering, but there are no Xbox consoles simply because they are inferior in my eyes.
