The amount of people who no next to nothing about TOR in this thread is amusing.
1. "WoW Engine" lmao. SWTOR uses a heavily modified proto-version of the HERO Engine, WoW uses a heavily modified version of the WarCraft engine. Not only are they not the same, they share absolutely zero code.
2. There is no voice chat in SWTOR, for free or subscribed players.
3. SWTOR combat at any higher level is incredibly more advanced than spamming flurry and force wave on KOTOR, you're making assumptions about the entire game at while your character is at a basic level with no advanced training.
4. The class stories are where the game really shines, most of these stories (along with the stories of your companions) are very well written, many easily eclipse the saturday morning cartoon good vs evil cookie cutter story of KOTOR 1.
5. SWTOR is unique in the MMO-field in that there is almost no grinding in the game whatsoever. You can get to max level by doing nothing but unique story quests.
6. There is never a reference to anything more than a strong platonic friendship and comradery between the Exile and Revan in SWTOR.
