Wanted to share some thoughts. I have played tons of MMOs, but mainly SWG way back and Wow.
I believe this places SWTOR 2nd or 3rd in the all-time highest preselling game. Top award of course goes to Mario Kart 7 which presold a staggering 1.3M copies. Point is, approximately 1 million people took the presales jump to in essence dive head first into the game. If the game catches on, early new year growth is inevitable. How much, who knows.
Statistics are hovering around a 97% 'love it' rating by beta testers. If that figure applies to be even 90% accurate to live players then I thoroughly believe this game could bring the same type of cult phenom to the market which wow brought years ago. Make note these statistics are higher than Warcraft had upon its release but I digress the market was very different then as there was no 'juggernaut' around at that time. I believe wow's only competitors at their launch were SWG and EQII which both had under 500k subscribers at their peak.
Regarding server stability to date and buggyness to date, I am pleasantly surprised. Warcraft constantly crashed and had bugged quests 1 in every dozen or so, but Blizz was good about it and gave free days for their errors. I have crashed once in SWTOR and haven't yet had any bugged quests. I'm sure they are out there but I haven't run into them yet. Gameplay and rotation for the consular class so far has been excellent. I can tell they spent some time on this.
Graphics-wise, I am in Tatooine at the moment and it is staggering. Very impressed. It's nice to have a game which fully uses my CPU finally.
