I have received a free code for previous Tex Murphy games and wanted to know which of them are worth ? I guess the one before Tesla Effect is the best since it has connection between the storys and the game begins after that.

Hmm, I think you should take UAKM or Pandora. Those are much better games (storywise) than Overseer (my humble opinion)...

To my mind "The Pandora Directive" ist the best game in the sense of story and riddles.

i've played all 3 and gameplay wise overseer is my favorite. it plays the most smoothly. i admit the story is the weakest of all three but it shows how it all began with tex. course that's a reason to buy it ever. i bought pandora directive because i haven't played it in almost 20 years because of it not liking newer computers (pre gog).

i am looking forward to replaying pandora directive as well as overseer. the only one i have no interest in replaying is under a killing moon. i never did finish that game and i didn't like how it played. i have seen all the movies on youtube though.
