Well after many a nudge... I have brought back a rejuvenated thunderdome game. Most of the rules are similar to what they were before. No bounties, 150 sectors. The one thing that is different is when you lose your ship you go into a 10 min time out and then you can log back in and do battle again. Gone is the time of having to re-register. Note if you want to be in the scoreboard, you have to register your profile.
You can get to it by going to http://thunderdome.aatraders.com
Good luck... Its crazy addictive!!!
