Congratulations! You’ve just described “Star Fleet Battles,” the Trek/TOS-themed tabletop wargame that did all that you alluded to - and much more - solely with pencil, paper and dice. SFB is an white-bearded great-granddad compared to GSB, coming on the scene in 1979 and still going today. Sadly, age does not always signify wisdom.
Imagine trying to play GSB on a solely analog basis, while doing what you had just mentioned - calculating energy balance due to damage - in realtime as that given turn of gametime progresses. The resulting mid-turn speed changes, juggling reserve power thru your batteries, shifts in shield-reinforcement power, and downrating of weapons took several minutes to do (at least), and when all was said and done you had just finished simulating a mere two seconds of realtime in crushing fanboi fidelity. I quit SFB eons ago, yet the memory of that sort “complexity for complexity’s sake” still makes me grind my teeth in frustration.
Understatement of the year; see above. I feel like the Ghost of Christmas Future as he shows Scrooge what will happen if he doesn’t turn aside from his chosen course. Turn back, darkstar076, lest you too would be consumed by the beast!
Thank goodness Cliff has sensibly chosen various levels of conceptual abstraction so that all of us (Cliff included) can just leap over such soul-deadening work and still enjoy the game.
