Man, I missed out on console/handheld gaming since like 2004/2005 when I got addicted to WoW.
I had a GBA with a handful of games: FFIV, FFVI, Tales of Phantasia, Fire Emblem(the first one), and I think that's it.
I have a DS. I have: Chrono Trigger, FF III, FF IV, and Super Mario 64. I had Magical Starsign for a bit based on NeoGAF hype but it wasn't that great.
I don't have a 3DS yet I see some titles that I'd play on it. I'd like to try the Zelda Link Between Worlds, Fire Emblem, etc.
I got a PS2 near the end of its life for FFX/X-2 but I only bought 3 games for it: Kingdom Hearts 2, Final Fantasy XII, and Dragonquest VIII. I only beat Kingdom Hearts 3
Skipped out on Wii/PS3/360. I have a Wii U and 3 games: Mario Kart 8, Super Mario Land 3D, Super Smash Bros. and Zelda: The Wind Waker.
I think my taste in gaming changed significantly after my Warcraft 3 / World of Warcraft addiction. If I was playing a game, it had to be with or against other people. I didn't want to be on my couch in front of the TV Playing a game. I wanted to be on my PC and accessible with the people that I played with so we could easily hop in and play together.
