Well that's three down...

I finally finished KotOR today.

I never did find out who reason that m character went all crazy and wanted to take over the universe, but at least I think i figured out what the "Battle mediation" macGuffin was about. It appears to be a way to give a Jedi's precognitive awareness to everyone on a side of a battle, making then much harder to hit and know what the enemy will do next (although this is never explained directly).

In the end I brought Bastila back to the light side of the force (she seems to switch sides whenever she is roughed up) and had the final conformation with Darth Malak. The final fight had to be done in 1 go since I found the hard way that saving partway in the fight crashes m game on load. The fight was mostly whacking small parts off his health then running away until I was "out of the fight" so I could spam health packs (also taking out his human batteries) then repeating until one of us was dead.

And so I'm declared grand super saviors of the republic and tomorrow it's off to play Halo 3.
