Actually yes i have. I'M a geek to in sci fi
Enterprise series by me was worst but its Star Trek lol there is no continuity.
Have you ever read the novels,Great Examples.I have read 3 diff versions of how Kirk dies lol. If Gene was still alive you can bet there would be continuity.
On a side note have you read the mirror image novel series by Shatner? if not you should its a must read and whoever the ghostwriter was really really new his star trek history.
