Err something like that. I was confused completly but was able to piece it together after an hour or two searching the Wookiepedia.
KOTOR, the first game I know we all came to love took place in...
3,956 BBY, during the closing of the Old Sith Wars.
KOTOR II, took place during
3,951 BBY, during the Old Republic Era and again, Old Sith Wars.
TOR will take place, instead of one year, it will span from
3,643 to
3,641 BBY, which is during the Inter-Sith Wars period.
So technically speaking, its anywhere from 308-321 years after the events of KOTOR, KOTOR one being 318-321, and KOTOR II 308-311. This is btw, after the events, TOR doesn't take place before, its after.
Honestly, the only question that comes to mind is where does all the technology go, you see The Clone Wars showing impressive stuff yet in the Galactic Civil War, you see these...err, I don't know, lower tech things? *Yet are somehow stronger than their predecessors, what?*
Newest trailer, besides the stupid Origin thing, makes me seriously want to reconsider...
