Dragon Crystal looks interesting, but perhaps too dated for me to enjoy.

I remember playing Columns a lot when I had my Game Gear, but I doubt I would get it again. There's just so many superior jewel-matching games now.

As for Zelda: Link's Awakening? As I've never played it, I do believe I would leap to have it on 3DS. I've always enjoyed the home console Zelda's a lot, but I've never gotten into the handheld ones. It's just so hard to go from Windwaker and Twilight Princess to the DS games. The console games are just. so. beautiful.
