we are definitely getting lost in the analogy so my response doesn’t really connect to sandbox, but the engine is not my primary concern when buying a car. My primary concern is not dying in a car accident. An engine plays a role there but things like vehicle size, brakes, safety rating, crumple zones, roll over cages, etc are my major criteria. I drive a crappy V4 engine, when a V6 would be better (I am no car guy though so maybe I am mistaken). But the trade off for us was a more affordable and safer car. Obviously the engine failing is a catastrophic event but I would rather have engine failure than brake failure. My breaks failed on an old jeep once and the only reason we didn’t end up dead or in the hospital was because it had snowed and I was able to steer in a snow bank so it slowed us till we stopped
And yet if something goes wrong with any individual safety feature, I'm sure you would not immediately stop using the car just because that one feature stopped working.
If the engine stopped working, you would not drive that car. (Not that you'd have any
choice, mind, but still.) Hence: the engine is of primary importance
for driving a car. Whether the engine is
powerful is not; whether the engine
functions is.
The engine is what makes the car work. A car with every safety feature in the world and no engine, or a non-functional engine, is a particularly elaborate statue or highly inefficient wheel-cart; it cannot perform the task for which cars are designed, namely, driving. A car which lacks safety features (or which has safety features, but they are damaged/nonfunctional/spent/etc.)
is still usable as a car, but won't be maximally safe.
So I stand by what I said: The car's engine is of
primary importance. Once the engine meets the minimum functionality necessary for performing the function a car must perform, we can move on to other critical, but still necessarily secondary, concerns.
Likewise, a game system needs its metaphorical "engine" to work correctly, or it fails to perform the function of being a game people can play. Once the core system performs at the minimum level necessary,
then we can start focusing on other critical concerns.
Further: "engine failure" can be just as dangerous as brake failure. If your engine fails while you're on train tracks, or in the middle of an intersection, or any of various other places, that is
just as dangerous as brake failure--just a matter of being the obstacle something else hits, rather than being the hitting thing colliding with some other obstacle. So a failed engine is no more nor less a safety concern while driving than failed brakes; you need both things for a
safe vehicle, but you need the engine to have a vehicle
at all.
