Hi, I've been watching these suggestions off and on for a while, and I have to say they're among the best put-together suggestions I've seen out of... pretty much anything, independent of game or the content being suggested.
Anyway, that said, I've generally gotten the impression that with journey's end terraria is done receiving official updates outside of balancing and bugfixes. Does anyone know if Izzabelle has spoken on this matter yet? I'm afraid that I haven't actually stayed current with her project, just stopped in every few months to look for updates and be amazed by all the pretty pictures.
