My first real go at an MMO, and a few of my thoughts. I have played a few MMO's (mainly FTP ones), just to get a "feel" of the type of game SWTOR would be. So my MMO experience is fairly minimal
Firstly, the voice acting. For such a huge game, to have it all voice acted out, really adds to the experience for me. I've played many an RPG and while acting isn't essential, quality voice acting does add to an experience and makes the "stories" believable. So credit where it is due, this is really excellent.
Graphics wise, I knew from trailers, it wasn't going to be ground breaking or realism. But, it didn't have to really. I wouldn't say I am overly dissapointed, because I like the way the game looks generally. While it isn't super high texture detail (certainly up close), it is presented very well. I find things like the lip sync pretty good, and the way your charachter (and others) move and interact is all neatly done. It is quiet tidy in that respect.
I would hope that in the full retail, maybe there is higher res textures. Because your armour/gear can look a bit bland and flat. But overall, I think the way they have gone works.
But graphics and voice acting is one thing, how the game plays is important. And if I am going to shell out for the game, as well as regular monthly subscriptions, then I need to be kept entertained. The game looking/sounding pretty will only keep your attention for so long.
I played up to level 9, and so far, I haven't been bored. That is a plus

The audio and dialogue, as well as the cut scenes I Have seen so far, make the world and situation I am in believable. And I am only scratching the surface. While many of the quests are go to location A and kill X, what else was people to expect, most I have done seem to have a meaning. Also, some of the quests I have done, are not so Black and White. You have an element of choice about what you want to do, and knowing Bioware, this can and will effect your "personality" and choices of quests in the future.
Which brings me nicely onto the conversations, and more choice of how you want to play. I couldn't help myself going to the Dark Side

. It just adds another dimension to the game, and your in game persona becomes a little bit more believable. You can respond respectfully, aggressively, or a cautiously (in most cases) meaning you can build up the person you "want" to be. This worked brilliantly in Mass Effect, and it continues here too.
A bit of the technical beta stuff then. I had no CTD's, now DC's, and no issues at all. Lag was minimal, and my FPS stayed pretty solid, only dropping when in a Taxi sometimes. People worrying about this though? New drivers will be out come game release, and a game of this size may well get some special treatment. I am sure come release (or very soon after) the game will work much better, and be much smoother.
Overall, I am impressed. As a fairly MMORPG "noob", I haven't done a lot of this sort of thing, so the majority of it is new to me. My sister is a big WOW player though, and she was helping me out with some of the finer details. I can see why people who have played WOW can say it is similar, and maybe feel like they have done all this sort of thing before.
Overall, I am impressed. Impressed enough to buy it? Yes, I probably am. I was intending to make a purchase, and it would have took a poor beta showing to turn me away. I like Star Wars, I like RPG's, I like online gaming. This seems like the perfect game for me, and I can't wait to get going "for real".
