First off, hey ^^/
Im hugely excited for 1.3 and Im amazed at the amount of content thats in there. The level of support the game continues to enjoy and for free!
You need to release something so we can give you money, seriously.
"Take my money" :\
That said, some things Im not feelin -
This kinda troubles me. One of the fundamental aspects of Terraria is creating spaces, and your home is your castle! I have underground lairs which I worked hard on and sometimes go AFK inside. That doesnt appear to be possible in an expert mode world. Im all for having a shake up in the monster dept, having some new ones that are more crafty at getting in - especially event monsters - would be fun. But otherwise, if Ive already taken into consideration the what and where Im building, so not up in the clouds, or in the bowls of hell, or dungeon adjacent, then I dont want monsters spawning within my walls!
I think expert mode is toggleable, based on what was said.
Dont like the over simplification of crafting in these cases. They are part of your progress and when you work to gather all the parts, it feels like you earned it. The key one especially, thats a huge nerf.
