For any game to be not like wow will be tough for them to succeed. Millions of players have played wow and quite frankly, its a system that is easy to get used to, for all ages who game. I think that you should be thankful that they are keeping it similar in that way so it will have a fighting chance. I think SWTOR will succeed cause its the first time Star Wars made an MMO that is comparable to WOW. You quest, you fight in dungeons, and there will be raid content. With hardmodes!
