Not sure if anyone has Terraria or not, but if so, I've started a server (stepping in nya's footsteps). If you want the info, pm me, because I'm almost always on, and the server will always be online.
I've tried Terraria and I found it pretty entertaining. I would join if I were a little bit more closer to where you probably live. I would lag too much.
PD: such a shame that creating a server and using a client takes up to 95% of my CPU :/
