I started playing this yesterday, its not a download its a game you buy and install. Its pretty fun, the gfx arent too impressive but that may be because of the settings im running it on. It started off like most other online rpgs, you choose a name, race, class stat points etc, then your placed into a gameworld, which can either be offline story mode or an online mode with PvP combat, which can vary depending on the server, also i thought it was quite unique because you can design your own Modules (Game worlds) where you can place monsters, items doors, etc. Currently im working on levelling up my character and learning how to use the toolset which allows you to create modules. Its worth a try if you ever see it.
Heres a trailer for it
