- Superb sound design
- A really robust engine for making tons and tons of Bells, the in-game currency
- No DLC micro transactions (This is actually a good thing, folks)
- The Island is a fabulous mechanic that works really well in the game
- A robust selection of tools you can use
- Fun stores
- A way to sell your items EVEN WHEN NOOK'S IS CLOSED! This is a HUGE improvement over previous games, and
- You don't have to jump through hoops to eithre donate items to the museum OR to have your fossils assessed! YEE HA!
- Online and wireless connectivity features that actually make sense
- Each animal in your town now has a custom house! You don't realize just how samey their houses were in previous games until you play this game.
- Really cool features (like QR codes) that make sense in the context of the hardware features of the 3DS.
- Truly some of the most annoying moments in the entire game are when you have to sneak up to catch bugs. The sneaking mechanic is kind of a pain in the butt when you cannot even use the D-Pad to sneak in that respect, and even then you might catch the bugs you want 50% of the time because of the weird arc that the net swings in.
- Another problem with the bugs in this game: Some of them are unbelievably annoying to listen to, like the cicadas (really I just want them to SHUT UP ALREADY)
- The fishing is also a painful mechanic as well but it's a LOT more precise than using the bug catching net.
