I played my first game of Battletech ever with my kids today. My five year old's Enforcer was soundly defeated by my Hunchback's AC/20.
My three year-old participated in the second game. Wisely, she and her brother formed a temporary alliance against dear ole Dad. As my son's Cicada maneuvered behind me, my daughter's Hunchback came head-on but could not engage my Enforcer hiding in heavy foliage. Her Hunchback took a lot of damage from my AC/10, as my son peppered me from behind. The Hunchback then plowed into the forest to face the Enforcer at point-black range. The Enforcer tried to flee the more heavily-armed 'Mech but cut off by the speedier Cicada and had difficulty maneuvering in the trees (sans jump jets for our simplified game). The Hunchback then mercilessly tore the Enforcer apart, and it's Mechwarrior was forced to punch out and take refuge in the wood.
The Cicada then turned on its once ally. Rather than stand and fight, the Hunchback decided, unwisely, to flee. The speedier Cicada was able to pepper the heavily damaged Hunchback from behind. Finally, a heavenly voice convinced the Hunchback to turn and fight. Losing the initiative, the Cicada found itself engaged the Hunchback head-to-head, and the AC/20 devastated the Cicada. Sensing an opening to, again, flee, the Hunchback made for the woods---all the time being peppered by the Cicada. Once in the woods, the two colossal war machines turned to face each other for a final time. Perhaps the Hunchback's targeting computer was damaged, we may never know, but all of its shots missed. The Cicada's skilled Mechwarrior then placed a shot squarely in the Hunchback's damaged head---killing the 'Mech in a single blow.
Of course, we played without heat rules (or a lot of other rules) and a lot of guidance from Daddy.
