Nintendo's handheld is a fantastic gaming device. So if you're thinking of buying someone more games for their 3DS, or a 3DS itself, here's a little advice.
DO buy a 3DS if your friend/significant other/mom doesn't already own one. Chances are there's something to be found on the platform that they'd enjoy. Especially with recent new additions of the latest Zelda and Pokémon games, it's hard to live without Nintendo's most successful piece of hardware. Plus, it can play all of the DS's games, too. And if you are considering getting someone a 3DS, definitely go for the XL size. The bigger screen is well worth it.
DO buy Pokémon X or Y—they're the best Pokémon games in the franchise, and a good starting point for newbies, too. With over 700 creatures to capture, train and play with, it's hard not to be charmed by this RPG adventure. Plus, it lets you dress up and explore its own version of Paris—Eiffel Tower and all—while riding roller skates. Yes.
DO buy The Legend of Zelda: A Link Between Worlds, because, wow, that's one good Zelda game. It's a sequel to the Super Nintendo's A Link To The Past, a throwback to old-school top-down Zelda-ing. But it's also a progressive Zelda that shakes up the series' formula by freeing you to do more things in the order of your choosing. And then there's the soundtrack. Incredible. Give this game to anyone you like. Withhold this game from anyone you hate.
DO buy Animal Crossing: New Leaf, a lifestyle more than a game and something that you can check in on every so often. Any kind of gamer—and non-gamer!—can find enjoyment in their mayorship. Or pick up Mario & Luigi: Dream Team. It's the year of Luigi, after all, and this portable entry puts the skinny Mario brother in a hilarious, trippy action/RPG romp. Really, just buy any of these 3DS games.
