The N64 was my first console, so it holds a special place in my heart for nostalgia. I'm really loving the PS4.
Super Nintendo because it's better than original Nintendo, and I have not played anything other that those two.
The explosion of JRPGs coming to the west over the past few years makes it hard for me to choose so it's pretty even between the PS2, the PS3 and the PS4.
Ps1/2 era for me. If I had to pick I would go ps2 due to finding online. I believe ps4 in years to come will be looked back on as this generations N64. It will be seen as iconic. They games this year alone!
Nintendo Wii, I like that it reads your motions. Wii U and Nintendo Switch look good but I don't feel like spending the money on them as I'm still having fun with the Wii even after all these years.
