My personal top ten 3DS games
1.) Fire Emblem Echoes (best fe imo)
2.) Fire Emblem Fates (not for everyone but has great customization to make every playthru unique with all the different builds you can do for every character)
3.) The Legend of Zelda: A Link Between Worlds (best 2d zelda imo, I really love how open ended it is)
4.) Shantae and the Pirates Curse (excellent metroidvania with fun writing and funner abilities)
5.) Pokemon Mystery Dungeon: Gates to Infinity (best pokemon fight me, excellent story and characters, and I really like building up the paradise. I still return to it from time to time to go on random missions to work on the pokemon paradise)
6.) Fire Emblem Awakening (very fun to play and replay with different pairings)
7.) Metroid: Samus Returns (strong return to form for metroid series, after no good games since the prime trilogy compilation release in 2009)
8.) Kingdom Hearts 3D: Dream Drop Distance (horribly imbalanced in players favor and the story is bad but flow motion and dream eaters are so fun to use)
9.) Bravely Default (major pacing issues but class system and brave/default mechanic make up for it)
10.) Mario and Luigi: Dream Team (good follow-up to original trilogy that evolves the mechanics in a great way BUT majorly held back by game breaking glitches in two late game boss fights, if not for that would be a lot higher on this list)
Honorable Mentions
Kirby Triple Deluxe (hypernova and moving between foreground and background

)
Ocarina of Time 3D and Majora's Mask 3D (great ports, make lots of qol improvements to OGs)
Stuff That's Been said and is on my backlog
Bravely Second, Kirby Planet Robobot, Rune Factory 4, Kid Icarus Uprising, Puzzle and Dragons Z, Dragon Quest 7, Dragon Quest 8, Metal Gear Solid 3: Snake Eater, Theatrhythm Final Fantasy
stuff that has been said that i MAJORLY disagree with
Mainline Pokemon Games - In my Opinion, Mainline Pokemon Peaked with BW2 and has been on the decline ever since
smt/persona - overly derivative of other games, painfully edgy, and more grindy than dragon quest, and while this probably wont matter for most of you all, but this is the most important reason to me: it espouses beliefs that are extremely against my religion
