to add to the circle / guild / warplot thing, you can still be invited in by others of a non F2P status. Also, if you paid for a month just to create all of them, then cancelled the sub, you wont lose access or get booted from them... you just wont be able to invite anyone else
I hope Carbine don't mess up F2P.
I know Lineage 1 and 2 but I also know about the fate of Tabula Rasa and Auto Assault.
I see a lot of people being very nervous about NCSoft's reputation with underperforming MMO's. I know little about Auto Assault but in the cases of Tabula Rasa and City of Heroes/Villains if you poke around you'll find references that paint very strained relationships above and beyond their respective financial issues between the development teams and NCSoft.
