Other:I am a dirty house-ruler who predominatly uses mechs, and hacks out Bt's shooting and damage system (with mods to AC damage) and pastes it inelegantly on Maneouvre Group's round sequence, and butchers 2D6 for shooting and piloting checks in lieu of using a D20 without changing all but a couple of modifiers. (And further compounding the heresey with remorseless pictorial evidence and aggrevated verbostiy
in the Fan Rules section)
Who plays mostly solo, but that's more because I only GET to play solo games infrequently at home (as - as of time of writing - Dad is playing moderns in the mancave with his mate); and at shows is pretty much liable to have to put on games with my own toys, not BattleTech's, since that is like my job and such.
A dirty house-ruler who WILL go to the extent of followig instructons on how to hack open MegaMek to implement said damage changes, and go through 2946 mech files (corresponding to all mechs owned) and check stuff and manually set pictures and so forth and painstakingly make subvariants with all guns forwards.
I am nothing if not
thorough in being a dirty house-ruler.
(And if you think BT has it bad, it gets away LIGHTLY; consider poor D&D 3.5 and Pathfinder 1, which get uncerimoniously hacked up and pasted together (with the odd gibbet of 4E and 5E and even PF2) to the tune of about 2000-pages of house-rules...)
I also play HBS BT and MW 5 (solo). (I also have played MW3 a moderate amount, never managed to finish MechCommander 1, despite it having the best cut-scene intro of any game ever (fight me) but has given MechCommander 2 the gold seal of Have Played More Than Twice, which places it is such esteemed company as DungeonKeeper 1, PlaneScape Torment, TIE Fighter, Sword of the Stars and Command and Conquer (1, 2, RA 1,2 and Generals). And I played MW4 a bit when a mate lent me it fo playing co-op.)
