I have played the first Knights of the Old Republic game to death years ago. Without mods, with mods, and even made a few myself, albiet rather... low quality ones. I loved that game so much lol I must've replayed the game about 50 times.
I just started KotOR 2 and it's pretty good so far, I keep getting lost every other quest or so though. (That's what I get when I skip dialogue and want to get straight into the action.) Choosing to do the evilest shit my "Jedi" can do, that's always fun
As for The Old Republic MMO, I'm pretty addicted to it. Played 48 hours almost non-stop, I haven't had this much fun in a long time. T7's healing is OP for PvE imo, I rarely lose any health. I don't know if I will ever join a guild or try PvP combat, still learning how to use mouse and keyboard to play games at a quick pace.
That may take some time... Probably never... I'm still a console peasant.
