DLC2 is shaping up
As I was coding for Forgotten Prison, I realized that once DLC2 is out, you could make an adventure game with NPCs and quests without ever touching code. It's all in the power of NetRadiant level editor and built-in mission editor!
The question is how to make people aware of such potential ? Although it's not MineCraft's ease of building worlds, it's certainly easier than UDK and other modern dev kits :)
