Help bolster my 3DS collection

[road doggy dogg]

A call to arms for my fellow gamers. I have been incredibly late to the 3DS party, and would like to hear your input on the essential titles I should be paying attention to.

As of right now I only have a Link Between Worlds and Pokemon Y. Both fantastic titles, granted, but I want to experience the full gamut of what the handheld has to offer. I have fallen off the map with my coverage of the system since it came out, but I know there are tons of games I am super excited about.

I'm pretty open to most genres and IPs, huge developers and indie alike. Even if you have a quick "top 5 must-have games" list, lemme see it. Let's have at 'er. Cheers ears and donkey tears.
