To anyone having doubts about this mod: don't.
At version 2.2.0 it does an exceptional job at delivering what it promises in the summary above. Much of the dialogue about you not being a Jedi is gone, some PC responses have been altered accordingly and it flows really well storywise.
Just an important note: if you are using any other mods that use/alter the dialog.tlk file make sure to install this one last, this way you prevent it from breaking storywise.
I wouldn't recommend this mod for a 1st playthrough, otherwise why wait to be a Jedi?
Will use this mod ALLWAYS
Absolutely required for any KOTOR run in my opinion. The average blaster is absolute trash even compared to a bog standard shortsword. The fact that this mod takes the changes that Obsidian made in KOTOR 2 and adds them to KOTOR 1 makes blasters somewhat more palatable in the beginning, which is fantastic for characters like Carth and Mission, who are pretty much perfectly geared for blasters.
