@Diddly, heh I played that version of EQ also (I still have my copy of that PS2 version), plus, before that I played on the computer. Then I did a little Dark Ages of Camelot, some Guild Wars, and a whole lot of WoW (I was on a top rading guild on our server before we all crash and burned of boredom/grinding).
Anyway, about SWTOR, when I did the BETA it was on my desktop which I am pretty sure I built it around 2 years ago and I made it near top of the line at the time - the game always ran smooth as silk for me during BETA. I am pretty sure this game does not require the most demanding of CPU requirements, but it also delivers.
The game is really easy to get the hang of, just remember to go find your trainers and train up when you lvl. I had no clue where the BH trainer was when I did the beta and I got to like lvl 12 with ease using like only 3 skills or something before I finally found him (I must not have been paying attention somewhere).
The only thing holding me back is time and money, and my weight (235-240)... lol! I am trying to get more active and this would do the exact opposite...
