I have been signed up on SWTOR forums since 09. During that time they have spoon fed us small bits of information about the game, little by little. I watched as the weeks went by and I did not get a BETA invite. My heart sank in my chest about this situation. Then finally, Victory! one day I got a beta invite. I used to be on the "cricket broadband" which is an extremely slow internet. It took me 3 days over straight downloading the game I never downloaded it all.
All day and night, it would be downloading. I finally had my feel and vented my frustration about it and boom I was kicked off SWTOR site for telling about "confidenal Information" really, confidential information? It's not like the CIA is going to war. People take things too seriously. I never even got to play the game.
My experience:
Their is a TON of data to download. Make sure you have a fast internet(download speed went at 120kb for me, it took 3 days and I still haven't installed a lot.
Make sure you have a bigger hard drive. I thought my 150 GB would cut it, not so. It's so much data. They actually require you to have at least a 250 KB Good thing I will be updating mine next week to 500 KB.
Their is HYPE for the game. But based on everyone in the beta who was in the game "LOVED" the game. This will simply blow your mind away.
