I kind-of agree that regular walls in reserved areas would be a bit too easy.
That said some kind of improved defenses in reserved areas would be nice.
Perhaps smaller walls with a hit point cap, or some other defensive options for the frontier (watchtowers, minefields, tank traps, outposts, etc.). The possibilities are endless 
Here are two suggestions that I have.
1.) Add a facing property to creeps that allows me to change what direction they are pointing without moving from the spot. I want to be able to take them on parade and look good in formations.
2.) I always like priests in Age of Empires. Give us the ability to convert other creeps to our side. Perhaps using claim parts?
Thanks.
Hello All,
I just realized that the end-game for Screeps is to create SkyNet. Are we all doomed?
