One of my favorite features oft SWG was the way you had to find a shifting source of crafting materials. I loved the use of probe droids, coupled with the survey skill to find a location of a resource pool.
You then had to pull up a sample and test the resource's quality and stats and decide if it was a place you wanted to slap down a harvester until the resource shifted.
The shifting of the resources gave you a reason to explore different areas, some fell in safe areas some in areas where you may need backup to place and harvest your materials.
I like the "land rush" part of this because the resource areas were ever changing. That and a limit to the number of harvesters you could place seemed to give everyone a fair chance to find the resources they were after.
I am not a fan of static nodes where everyone is fighting in the same area waiting for the respawn to pop.
I know The Repopulation has crafting mats with different stats but they are static nodes as well (at least last time I played).
Why don't we see more systems like this? Am I in the minority? Are there games with something like this system in it?
