You know, I think the one I've had the most fun with was the original multi-line (TOS). The only Flex-Range one I've played so far is ToA, which gimped a bunch of other features to emphasize free-running and often ended up a little bland as a result. I assume when I play RM and TOSKOR, they'll do it better. (Haven't played ToI yet either.)
ToDr's was really cool though. Guess I'll vote for it.
But Tempest wasnt THAT bad, that is true... I think that what ruined it was that there werent voices and the playtime ugh, 10 hours of play?
