Nope, haven't played another since I put my GBA away! :P
Yes, actually. Well, mostly Nintendo games. I've been downloading some older GBC titles for my 3DS's Virtual Console lately, and I'm shocked how many titles I missed. I actually had a GBC, but I only used it for Gameboy games. I've discovered a lot old gems like the Zelda: Oracle games (which I actually got last summer) and a few MegaMan X side-titles I didn't even know about (collectively, they're known as Megaman Xtreme).
Alternatively, I did come across an interesting RPG series last year for the DS/3DS that I had no idea even existed. It's called Etrian Odyssey. I only tried the demo of EO IV: Legends of the Titan on a whim, and was totally addicted right away. The main premise is that you are a wandering explorer who came to town seeking to find out the secrets of the holy tree known as Yggdrasil (named after ancient tree in Norse mythology). In the games collectively, Yggdrasil was supposed to be an attempt to save the world in a time where technology, war, and pollution got out of hand (i.e. just after the modern age). In the centuries after, the world became more primal and humans regressed to a feudal society (some technology still exists, but it's a far cry from what it was). The gameplay itself is mostly dungeon crawling mixed with old RPG aspects. Also, the games are intentional hard to put for a challenge to serious players (EO IV and EO Untold allow you to change difficulties, but I didn't because I actually want to play them through on Normal difficulty, which is actually Hard).
