https://www.boardgamegeek.com/boardgame/3616/battleforce was the best version of Battletech.
The actual design rules in Battletech made almost no sense. Just off the top of my head, from 20 years ago, i can remember that PPCs and AC/5s weighed the same and had the same range, but the PPC did 10 damage for 10 heat, while the AC/5 did 5 damage for 3 heat. But this means you need to carry ammo for the AC/5, increasing it’s effective weight to, let’s say, 9 tons vs. the PPC’s 7. This means that the AC/5 “costs” 3/5 a heat point for every point of damage, while the PPC “costs” 1 heat point for every point of damage. But because the PPC weighs less, for the same weight you can get 2 extra heat sinks. 2 PPC’s means 4 extra heat sinks. Now if you simply alternate firing rounds; that is, only firing the PPC once every two rounds instead of every round, you get 1 point of damage for every 1/2 heat point, and you are dissipating 4 extra points of heat (2 heat sinks (2 rounds)). And you’re not vulnerable to ammunition explosions. Why would any military chose to ever use AC/5s? The whole game was full of these problems. Like infantry. Oh man, infantry are nearly free in the Battletech universe, but Mechs are “irreplacable”. But infantry do like 7 points of damage for ever 28 men. Screw mechs, just send in the human waves and win every time.
Sighs. It was a sad day in college when i took my duffel bag full of Battletech and set it lovingly in the dumpster, never to see it again. One has to grow up at some point, you know.
