You're conflating "game engine" with "game" here. And YES, there is very
Game engines *MUST* be *EFFICIENT* in order facilitate the demands the
games place on them. And "efficiency" *means* efficiency: it means
minimizing wasted processing, and that *inherently* means *both* speed
The *games*, not the engines, then take that efficiency and use it to
fill the hardware to the absolute brim, maximizing detail and data and
overall lushness of the simulated world (and, in the case of indie
titles, it's also increasingly used to offset sloppy game code - with
engines like Unity, indie game programming is increasingly done by
people with very little programming experience). THAT is what kills
battery: Taking an otherwise efficient engine and using it to saturate
the hardware, thus trading battery for either maximal data being
processed or for lowering the programmer's barrier to entry.
Due to the very nature of "efficiency", the fundamental designs behind
any good game engine could just as easily be applied to minimizing
battery usage as they can be to maximizing CPU/GPU utilization.
