I don’t think the sequence of registration matters so much as whether there is trademark infringement. If there is trading on the name of a trademarked brand then you would have a case to get the domain transferred.
However, I went to http://www.sci-fi-casino.com/about.asp and it is not obvious that you have trademarked the name.
My limited experience of these situations has been that most people don’t want any hassle and just settle these things. But a low-key approach works best!
Casinoblasters has a toll free number and the team are super responsive so I guess they are at ICE.
If you want to get aggressive about this use reverse ip look up at whois.sc and check out other casino operators…e.g. I can see all 40 domains on the sci-fi server…If you do the same on some other operator servers it is quite amusing to see what domains they have registered.
