What should be done about random engines

[Glamurio]

I quite like random engines, though I'd prefer the "choose your own engine" approach we had solidly for a bit. As opposed to many other jobs, engineers often have to make the additional choice of "do I want to play this engine" vs. "do I want to play this map". By mixing up engines, it gives the department a bit more control about the way they want to play, which is standard for all other departments.
