Dear Gree, Please consider this idea.
How about a contest to see which Faction/Person can gather the most money. This event has both Offensive and Defensive elements. Offensive: Raid or Attack other players to gather money like we do now. Defensive: Each Player must continually monitor their cash producing buildings, collect and protect their money in their vault. This game would not look at money stolen nor would it only look how much is in your vault. Soon after the event players will quickly exceed their vault limits and be good targets for other players. The only way money would "out-of-the-game" is when its donated to the Faction or used to buy units.
Each dollar gathered, regardless of how (collecting & raiding) will count toward the total. I think this a new and exciting idea that could be a great fun. Please post improvement ideas on this idea.
Thanks, HMG
