I have trivial pursuit (forget which edition, but its an older one), the anniversary edition (20th, I think) and Star Wars with DVD. To answer the question about is the OT and PT intertwined, the answer is yes. I suppose if you really wanted to, you could play OT only by skipping any questions dealing with the PT, but that would be harder still with the DVD, because you may not know if the question deals with the OT until its over. (such as 'guess who's voice' type questions). The anniversary edition is really hard, and we never play it as a result, and usually end up playing the older one we have.
