Rocktropia is the second planet started. It stumbled pretty badly out of the gate, but has retrenched and come back strong in the last couple of years. The RT starter missions are pretty pedestrian, and for a long time they were broken. But that didn't matter, because the real starter mission chain was Hunt the Thing, widely held to be one of the best and funnest mission chains in the game...possibly the best and funnest. Rock doesn't have that many people, so it can be hard to sell loot there. Having said that, there is a lot there for the new player...haters to sweat, vixens to grind, and zombies to kill. You can also hunt papoo on Secret Island, just make sure you have a banana to get back. The main thing to note about starting on RT, is that you don't. Neverdie made a deal that players that start on RT go to Thule, and then to Caly, which I think was pretty damned decent of him. So starting on Rocktropia is exactly the same as starting on Calypso, with two exceptions. One, your avatar gets a cool looking tee-shirt, which looks better than the OJs. And two, you get a one-time, one-way teleport to Rock from Caly. Do NOT talk to the npc unless you are ready to go right then.
