Street projects are nice and all, but imo they are too short and lacks impact on the game world other than opening a new (all too similar) street which you probably will only visit once in a while anyway.
I'm proposing a new kind of project which dwarfs street project in terms of scale and impact on the game world. Namely the Monument/Wonder Projects. These projects will require considerably more resources and work than a typical street project to complete. It will also covers a wide range of resources and work type. Special unique requirements can also be thrown in. I'm expecting at least thousands of Glitchen contributing on a single project (of course, you need to think of the lag problem...). The result will be a unique monument/wonder perhaps akin to Jethimadh Tower. And whereas a street project opens a single street, a monument/wonder project will opens up an entire unique region/area. This monument/wonder region could have special properties, for example more effective meditating in the area, etc. The rewards for those who contribute will also be greater and perhaps give special bonuses to the top contributors. Like double yield mining for the first X picks per day for the top X contributors for completing the Monument of Zille or something like that.
This idea may be hard to implement but for me personally it's a very exciting prospect. It also enables player to be more involved in shaping the world of Ur. Imagine building a Pyramid like structure with your fellow Glitchen in Ur.
