I own 3 games for the system and would recommend them all, sorta.
Zelda: OoT 3DS - It’s OoT. A great game and a great port.
SSF4 3DS - a really good version of SSF4. Controls take some getting used to, but the entire game is in there. It’s actually really impressive. All the characters, moves, combos (that I can see), modes, etc. Don’t bother if you’re not a fan.
Ghost Recon Shadow Wars - a really deep, involving, and enjoyable turn-based strategy game. It looks a bit rough (I think it was originally meant for the DS), but there’s a ton here.
I’d also recommend Zelda and Street Fighter. And, if you’re into football/soccer, Pro Evo. The features are pretty basic by modern console standards, more like PS 2 era but, hey, it’s Pro Evo on your handheld.
I purchased this starter kit, mostly for the carrying case, game cases and the car adapter, but have gotten quite a bit of use out of the larger pen-type stylus as well. The headphones aren’t very good, as you might imagine, and I decided not to use the screen protectors. All in all I think it was worth the relatively meager asking price.
Game wise, I can also endorse Zelda: OOT and Ghost Recon: Shadow Wars. I also have Ridge Racer 3D, which is a decent racer, if a very arcadey one. Not spectacular, but for $20 not bad if you dig that kind of thing.
Hey, I just bought a 3DS too! I only bought Zelda so far because I think that’s the only game available so far. But I will be grabbing Starfox pretty soon, and whatever new Layton games will be coming out.
Yes, the rumored add-on is in fact real and was revealed in Famitsu along side a 3DS version of Monster Hunter Tri. It’s enormous, ugly and adds 2 extra shoulder buttons as well as the right analog control.
Presumably Nintendo is laying the ground work for when they redesign the 3DS to include a second analog control so developers can take advantage without early adopters being orphaned.
Of course, instead of selling this monstrosity they should probably just own up to their failures and offer to exchange original 3DS systems for the new model when it comes out.
