We sorta have the opposite problem; I have hands that resent their given function, hands that flop and writhe, hands that are happy to cover an entire PCB in a thin layer of solder when trying to join a single junction. He has perfectly still art hands. If I'm gonna undertake the kind of labor required to build a bunch of models, there has to be a scenario where I arrange said models with precision, roll well, and still lose somehow. Sorry! That's how it's gotta be.
Of course, there are in fact sophisticated indie rules for Gundam at at the 1/144 scale - once you really start getting into the hobby, at a certain point the floor falls out and you start discovering Model Agnostic Rulesets like Frostgrave or Chain Of Command which only multiplies the utility of your collection.
There's nothing I love more than reading wargame rules. Yes, it increases the chances of me snipping a bunch of sprues and filing them and painting them if they bloom into some kind of simulation later, but the truth is that I have read and learned to a pretty high degree probably five wargames I'm not sure I'll ever play. I talked about this in the post for the Professor Layton comic, the one with the Tvelve Metchsteeks, about how what I like about these games are… well, the games, I like those too, but it's the almost ritual preparation of my mind to even get it into a state where assumptions don't occlude analysis. A sentence like that is how you know I just got my second shot and spent all night sweating through my sheets. I better go back to bed.
