I'm going from another game that is closing down soon. That game you gained skill based on using that skill. There was hunting perps, and all sorts of other things you can do like playing instruments, mining, fishing, crime solving.
So far, all I can tell for this game is getting a job and RPing it. What else is there to do?
How is experience granted in Sindome?
There is LOTS to do. Some jobs are just there to provide an income and support your real RP. Some jobs are awesome to RP. Some jobs aren't coded or admin-supported at all but entirely player-created, player-driven and player-demanded.
