I know there's already a thread about this, but, considering the circumstances, I'm thinking people's ideas on what they'd do would be best kept in a seperate thread.
If you were Dev for a month or two, what would you try to do?
Me, I'd work exclusively on making story access more open to players by putting the actualy physical condition of the Matrix into their hands, using conditionals and player tools that affect how buildings look, where missions are more likely to take you, and even the general atmosphere.
For example, a bomb tool that, if activated and nobody heeds its warning, will destroy part or the entirety of a building. Debris would be spawned all around the area until the weekly maintenance, where the texture of the building will be changed (or the building replaced by a pile of rubble) to signify the change. Over time, the Machines would rebuild the building until it's useable again, and obviously some buildings can't be destroyed. This could result in some fanatical evil doers laying waste to a city whilst the goody two shoes work to stop them.
Amongst other things, one-player-item types that would seriously affect the environment (change the color of the skies, for example) and give that player some special powers, and it would be up to other players to either aid him or destroy his power (or take it for themselves).
And a special blog on the official website recapping stunts like this every week!
It's all very vague, and actual details would have to be extremely specific to avoid exploiting the system and whatnot, but after all, it's supposed to just be a vague "If I were God for a day" type dream.
