I think form an RPG perspective the game is a success. It has a rich and clear main story and even the side quests (the grind) are savely embedded into cut scenes and dialogs to be enjoyable.
Haven't tried PvP yet and probably won't get too much into crafting and economy stuff.
I am ultimately spoiled by Cryptic's character creation tool that allows infinitely better customization of your toons.
Even DCU Online, where you had pretty boring starter toons, let you customize to a much better degree by letting you keep costume parts of any gear you unlocked.
In TOR the look of your toon is pretty much dictated by whatever is the currently best available gear.
As a bounty hunter for example you are esspecially screwed because it won'T take long for you to find a helmet that obscures the head (the only body part where some decent customization happens).
