I sure do. Games like: Super Mario Land 3D, and Pokemon Rumble Blast are keeping me busy. I can't wait for the upcoming Mario games to come out. I'm still waiting to hear any news for the system's first main handheld Pokemon adventure.
I was an early adopter, so I gladly got the free games. Other than those the only 3DS games I currently own are Pokemon rumble and Mario Kart... I mostly use it to play the regular DS pokemon games. That will change soon though.
I got mine last Christmas and haven't had much use for it in all honesty since I only got SM3DL and LoZ: OoT and for some reason they didn't hold my interest for too long. My birthday should bring an influx of at least three games I'm excited for, though, so fingers crossed it'll finally make itself worth the cost. Kicking myself now, really, because when I was frantically deciding on colours before christmas I didn't know they'd be bringing out a purple one. I love my white one but damn, purple is my favourite colour! D:
Still using a DS Lite, seriously considering the upgrade though. I've played one owned by a friend, it's surely an elite handheld device. I'll see about it this Tuesday, I'm not swimming in money however so it is pretty doubtful that I'll end up getting one at this time. My birthday does happen to be coming up in a couple months so I imagine I'll be getting one with whatever money I muster up from gifts I may receive.
