This thread will have a very simple point. Just take what you know about Outerra and describe what "Game" you would like to play out in the world.
==========================================
My idea is pretty simple. Back in the day I was a HUGE fan of Interstate76. Auto Vigilante combat at its finest. The maps were huge sprawling desert roads through what 1997 graphics could call mountains. The year is 1976 and you are recruited to take the place of your recently deceased sister and avenge her death. You join her partner Taurus and mechanic Skeeter to continue their mission of revenge and proceed to murder crooked cops and other baddies with your armored up and armed muscle cars until you find the man who killed her.
Here is the intro
The game had a good story, just the right amount of humor and at the time realistic driving physics. Oh, and you "never get out of the car"..
Now, 13 years later I envision a massive multiplayer version. Baddies, Creepers, Vigilantes, Crooked cops all playing "Somewhere in the Southwest". MMO's are all elf, middle-earth cookie cutters of wow. Put some realistic driving physics and ballistics to work in the Desert areas of outerra and I can see gangs being formed, Drug cartel's taking over and You will need to choose who you are in this hellhole. Hundreds of miles could separate your next target. Maybe you need to protect a convoy carrying precious fuel for a long haul. Get the munitions from the airport. Fly the plane back over to Mexico. Etc Etc
I am sure more will come to me with this concept. I will edit this post with my ideas.
=======================================
Now you post your ideas for use of the OT engine.
