I caved in and preordered a new 3DS.
Anyone know of what the good stuff is on their eshop?
I haven't owned a Nintendo handheld since game boy advance. It's been awhile.
There are a lot of good games on the eShop in a variety of genres and styles, from small to full-fledged games, wether they are exclusive or not. All of these are good games that are frequently recommended to people asking the same question as you, so it's usually very easy to find more information about them. Check them out on the eShop itself, or google them and look for youtube videos, whatever is more comfortable for you, and I'm sure you'll find more than a few that catch your interest.
All of the Guild 01 or 02 games are very interesting, specially Attack of the Friday Monsters and Crimson Shroud, which are widly considered among the best games on the eShop, but at least Liberation Maiden and Weapon Shop de Omasse are also worth taking a look at. Yumi's Odd Odyssey (Sayonara Umihara Kawase) is a puzzle/platformer and one of my favorite games on the console and I wholeheartedly recommend looking into it. Phoenix Wright Ace Attorney Dual Destinies is another excellent game, but you should definitely play the previous games on the series, which are also available on the 3DS as a trilogy compilation or through its backwards compatibility with the DS.
Azure Striker Gunvolt is an excellent, very good looking game. Mighty Gunvolt is also worht playing, but it's much smaller game than ASG and plays very differently to it. You've probably already played Shovel Knight on PC or Wii U by now, but in case you haven't, it's a fantastic game and looks beautiful on the 3DS. Shantae is another very pretty game that was also very well received. HarmoKnight is great mix of rhythm game with sidescroller, by GameFreak. Fluidity is a very interesting game by Curve, the developers of Stealth Inc, published by Nintendo. Sakura Samurai and both parts of Dillon's Rolling Western are Nintendo published games that you should probably look into. The Denpa Men games are very quirky, very interesting RPGs.
Pushmo and its sequel Crashmo are excellent puzzle games by Intelligent Systems. Both Mighty Switch Force games were very well received. Every game in the Picross series is automatically among the best the puzzle genre has to offer. Tokyo Crash Mobs, Kersploosh and Alien on the Run are other decent puzzles worth checking out. Mario and Donkey Kong Minis on the Move is another fantastic puzzle game with a crapton of content. Art of Balance Touch is another great puzzle.
Kokuga is a good shooter by ex-Treasure people who worked on Ikaruga. I've heard good things about Nano Assault. Steel Empire is a good version of an old Genesis / Mega Drive game, if a bit pricey.
There's a free version of Steel Diver Sub Wars that's a lot of fun if you can play multiplayer, but even if you don't it doesn't cost anything, so give it a try. Rusty's Real Deal Baseball is another fantastic game, some of its games are extremely addicting. The StreetPass Mii Plaza games can be a lot of fun, depending on how many StreetPasses you think you're going to get (or if you can set up HomePass). Pokedex 3D can be great or useless, depending on how much into Pokemon you are.
Then there's a whole bunch of great Virtual Console games, of course, as well as some very good DSi games. The 3D Classics collection is very good, even if just as a curiosity, and they're the best version of those games available. Sega and M2 did an excellent job with the 3D versions of classic Sega games and they have a great price, so definitely check them out as well.
I know I'm forgetting some games but I'm sure others have already mentioned them, or will. There are also some smaller games, like those by G-Style, that are well liked by the few people I know that have played them, but I haven't really looked into them.
There's a lot to like on the 3DS, wether its digital or physical games, or from its full compatibility with the DS's library, one of the best any console has ever had, handheld or not.
Are you crazy? XD I wish I had money to own all the games I like on the eShop. I've been very lucky lately and played a few games I wouldn't have been able to under different circumstances, and I'm very grateful for that, but there's a lot of interesting, fun looking games in there, man.
