(Some quick background - I beta tested and played SWG until the NGE nerf. I beta tested and played World of Warcraft up until about 18 months ago. I have also played multiple other MMOs including DDO, Ultima, Tabula Rasa, A Tale in the Desert, and so on.)
It actually IS this awesome new MMO experience, and please stop WoW fanboying by playing down the impact of the fully voiced universe and the fact Bioware has done what Blizzard did - borrowed from the best of in other MMOs and refined it. As dward90 says above, if you're skipping the voiced scenes then you're missing the point.
It is definitely NOT WoW with lightsabers - I don't see any orcs, goblins, or pandas running around. Oh? You mean it PLAYS like Word of Warcraft somewhat? Yes, it does. In as much as World of Warcraft played like Star Wars Galaxies, and Ultima Online, and Asheron's Call, and the other MMOs that came before it.
I have been in multiple betas of SWTOR and I have been playing since December 13th of early access. I can tell you now, this game has longevity and inventiveness on its side. It is fresh and new and compelling in ways that other MMOs "walls-o-text" quest/missions are not. It engages you in both your class storyline and in the world at large. It doesn't have the sandbox open worlds of an MMO like Galaxies or an RPG like The Elder Scrolls series, but there are hints that Bioware may be moving that direction as the game grows. The game is great visually and gameplay is engrossing. The mission/gather system is an amazing combination of previous MMOs like Eve and WoW. The crafting system is fairly solid, interesting, useful and will come into its own as more players inhabit the universe and expand the player economy.
As for the so-called "end game" that hard core players and game sites seem to want to focus on, well, that will be a while in coming for casual gamers like myself (although my main character is level 22 at this time). Those hard core players with no life and a caffeine drip in their veins can probably give you a review in another 5 days or less :-p My hope is that Bioware ignores their outcries when they consume the game inside of 14 days and start looking for something else. Your revenue stream is NOT the hard core players, it is the casual gamers who will play for years on end.
