Official Terraria Thread

Alright folks, I know a bunch of us bought this in the Steam sale and I've seen people playing it like crazy. What are your thoughts so far?

I think the game is insanely deep and ambitious. I've played a few hours and feel like I haven't even scratched the surface. Multi-player is a lot of fun as well. Perhaps we can get a GL server up like Havaak was so kind to host for Minecraft.

EDIT: helps if I spell the name right in the official thread title, lol.
