Lots of straight up god tier games in this list. Just goes to show how amazing the 3DS is when I saw at least a dozen games I wanted to replay.

One I will say I think deserves to be on the list though that's criminally overlooked is Ace Combat Assault Horizon Legacy+. As a remake of Ace Combat 2, it does a fantastic job of updating the original to be more in line with the holy trinity (04, 5, and Zero). It has both arcade controls for newcomers and classic controls for fighter jet lovers like me. And if you don't like the new combat maneuvers, the game lets you just turn them off. The soundtrack and sound effects are, especially for a 3DS game, incredible. Some of the explosions like when you shoot down an enemy jet are pretty amazing for the 3DS as well. The game doesn't have multiplayer, but if you're a single player like me you won't really care. It also has a pretty impressive selection of planes from across the series, and the extra control features and Nintendo aircraft added in the + version are much appreciated as well. Even though the original game was released in 2011, it's still one of the most impressive games on the system to me. I just wish the game would have gotten the Resident Evil Revelations treatment so it would be on consoles now (especially on the Switch).

Another that I feel was a bit underappreciated and even treated harshly was Splinter Cell 3D. Chaos Theory is my favorite stealth game I've ever played next to Splinter Cell Blacklist so I can't say no to a portable version of it. It's a port of the GameCube/PS2 version rather than the similar but ultimately better Xbox/PC version unfortunately, but you won't mind much if you love the game like I do. It even has features no other version of the game has, like Fusion goggles (combining night vision, thermal vision, and EMF vision into one viewing mode so you aren't having to juggle three viewing modes). Also, instead of selecting from one of three premade load outs for each mission that can't be changed, you unlock Sam's gear as you go through the game, and you can use it all in earlier missions. So previously impossible scenarios like having the shotgun and sniper attachments in early missions like the bank becomes a possibility. Really fun if you love all of Sam's classic gadgetry before Conviction and Blacklist made your equipment a bit more generic.

@Miiamoto Glad someone is mentioning Shadow Wars. Fantastic strategy game especially if you prefer a more high tech aesthetic.
