Let me refresh this topic a bit
An Olympus Arena in Mars orbit - I think that name tells much about the idea and is adequate IMO ;) Why Mars ? Well I think there is no better place in known AG universe to make duels/wars between "gods" than Mars.
Summation:
-TIMERS- of course these should be as short as possible. Maybe 1hour max so if any players would be interrested in observation of current duel/war they would have few minutes to get there, after some announcement in AG News would appear to all
-RULES-maybe some additional interface could appear when players who are about to make a duel/war there meet in orbit/arena station. Through this interface all rules of duel/war could be set; rewards discussed an agreed; which players and how many of them are involved in duel/war; what weapons are allowed and maybe power limits etc.
-AUDIENCE- Mars orbit should be available to all; players who would not be involved in duel/war but present in Mars orbit could be watching happenings in some kind of real time and get a highly detailed duel/war report; other players who would not be present in Mars orbit when duel/war take place could get a shorten report through AG News
-PERSONNEL-after duel/war any lost personnel should/could ;) be restored to involved players by AG system for free, or not
-BETS- these could be done in arena station through additional interface; maybe some % of total bets could be added to reward for a winner and/or taken from loser
-SURFACE- could stay available for all as it is or, when duel/war is taking place could be a part of battle to drop a fortress there maybe or something
Let's make it happen
