The dedicated servers are probably online most of the time.
Sadly I don't know anyone who could/would host a server for TBT. Right now people will probably have to decide on a dedicated server or host their own so they and their friends can play.
Starbound has dedicated servers for people to use. There are also a lot of other servers people host on Reddit and other places, but I'm not really counting on any of those being dedicated just to TBT. For that you'd have to find someone on here willing to host, and I dunno how likely that is.
Starbound is such a fun and addicting game, my friends and I played for a little while. I hit this wall where I felt like there wasnt any more content. This was around when the game was first released. Since the game I think deleted all the characters, and I'm just waiting a while for a couple more updates for the game to REALLY start appealing to me again.
Can any one vouch? How much more fun is it now compared to how it was when it first came out?
Same thing with Dr J. Waiting for a progression update before I start playing again.
On a related note, I adore the soundtrack greatly. It's definitely one of my favorites.
Got the game a week or two ago and beat the last boss recently, so I'm also waiting for an update 'cause I can't think of any more things to do. It's definitely a fun game though, I love these sandbox/survival games.
