One of the things I love more than anything in Star Wars:The Old Republic is the story telling. Normally I am not a lore nut. In fact, I am quite meh about it. Sure I know my WoW lore (some of it) only from playing for so long and now writing about it for OnRPG but it has never been a big part of game play for me. SW:TOR is different probably because I am actively involved in the story. I am making the decisions on how my story plays out. This morning, for example, I could have set the Major's son free but instead I killed him and stole the weapon he was trying to get. When I had to return to his father, I ended up killing him as well. The point is, I could have done it differently but I made a conscious decision to go the very evil route. I love that about SW:TOR.
So now I am just finishing up on Balmorra. I found a vendor that I could buy ship bits for my ship so that has made space battles much easier. Though on rails, I still find the space battles enjoyable.
