I used Steam to download the game. It took about 35 minutes. Patching was fast.
Steam is no longer available as a DL option for STO. A torrent version may be added to the current download options at a future date, in line with other current PWE games. Educated guess there, really.
PWE generally only makes their game clients available for download via their respective official sites, but there have been exceptions (Such as, CO is still available on Steam....lolwut? That appears to be a leap of illogic that would make Surak's head explode [Please don't shoot me if I got the founder of Vulcan teachings wrong, my Trek lore is rusty as an old gate]....)
Yes, STO originally had a torrent download on the download page, but it's gone now. I have a mac *is ashamed* But there's a fix so that I too can enjoy the game, but the official downloader doesn't work, so I have to use more direct means.
