How is it possible that a game with that kind of scope can be made by 4 people? What do you think their secret is?
There are many possibilities.
-They have some really powerful, but simple and easy to use engine.
-They are actually secretly getting help from more people.
-They are actually really freaking talented devs and hard workers.
-A combination of 1 and 3
-It's not actually nearly as robust as it seems.
What do you guys think?
