I'm glad to see that updates will be a thing on the 3ds version of this!!! Some things that I noticed that I'm sure that have been brought up before as well.
1. You can not mix biomes to allow for AFK farming for key molds. Tried making some farms with different biomes, but only 1 was active at a time.
2. Being able to rename chest would be a must! I forget where I put stuff all the time.
3. Higher tier accessories would also be nice. Like being able to combine the Moon Shell with the Celestial Stone like you can in the PC
4. Drops rates. My son manages to get all the rare Drops on the first try. And I end up farming for HOURS to get the same.
5. Events (Solar Eclipse Mainly) almost never get it.
6. Bosses De-Spawning if they are out of the screen. I'm still within their firing range, but they will de-spawn if you get them out of your sight sometimes. Happened with the Duke Fishron quite often.
7. Being able to zoom the camera out, so you can see a bit more to the world. Also watches and GPS Would be a nice touch. Hard to tell when it's night time. I know you can move the camera around on the N3DS but it's tough to do when you are fighting or moving around without it messing up what you are doing.
But I love this version of Terraria, the controls are fantastic, I love the portability of it, I like being able to play with my kids, and am looking forward to (hopefully getting) online so I can play with friends and family cities and states away!!!!
Keep up the good work!
