This was, I believe, largely a problem of marketing. It was, and is, entirely possible to play TOR as a single player game. My Sith Warrior playthrough did the following multiplayer events before reaching level 50: Black Talon once, Boarding Party once, and Foundry once. No heroics, no pvp, nothing. The game can be played in an entirely single-player context (heck, prior to server consolidation it was occasionally possible to be the only player on an entire planet sometimes). Played this way TOR is admittedly somewhat repetitive, since you go though effectively the same battle with simlar mobs over and over again, but that's hardly different from most single player rpgs - how many bandits do you slaughter in a skyrim playthrough? - but it is a perfectly satisfactory single-player game. When free-to-play comes out Bioware needs to emphasize this. No one wants to pay subscription fees for a single-player rpg, but with free to play, there's no need, and the game has easily 200+ hours of content just playing through the Republic and Imperial sides once. The story content is good, and fans of KOTOR should give it a shot when that happens.
