This is kotor. and kotor has never been a sandbox game and will never be
Regarding the second part of your post, you're correct; KotOR has never been a sandbox and never will be.
Regarding the first part, I've played through KotOR I and II around 20 times each in their entirety aaaand this game isn't KotOR, or anywhere remotely close to it. KotOR is actually an amazing game... This is a VERY mediocre game in every way possible except for the voice acting (which is great).
