Now a laughing stock...
If you are interested in an immersive online experience, with servers that are actually populated, try World of Warcraft. This game, SWG, is in its deaththrows. Even at peak gaming hours, the servers are lightly populated and this proves true when one logs in and attempts to find a group (which are a necessity with the new game engine).
This game used to be unique. With the new changes, things have become dumbed-down to the point of console-like simplicity. If you are interested in checking this debacle out, wait for the Xbox/PS version which is surely on the horizon. (Only console players could be forgiving enough to allow this game to succeed.)
