I find one of the most time consuming things is creating the damn logic over and over and over again. I think there should be "community" maps that have pre-built logic systems, so people could download and just start making the actual map. I think this would be useful, but do you think it's a useful endeavor?

I have logic systems for a Gears of War horde mode wave system (1-50) released already, and someone just needs to download the map and place the trigger in whatever room they want the event to occur. They can also fiddle with the spawners and everything if they want.
