Oh so it's a Sim, not a Simulation. Because Sim... means... Simulation? I'm sorry but who ever wrote those words lost me.
It's like this:
People that back Star Citizen in it's original campaign wanted a "Space Sim". A Space Sim is as follows:
Elite
Frontier: Elite 2
Wing Commander
Freespace
Freelancer
i-War
X-Wing
There is also another category of games called "Space Simulators". These are games such as Kerbal Space Program, or a NASA Shuttle Simulator.
They are not the same thing...
