All great points. I was actually considering splitting the rp into different threads, one containing the main storyline, while another contains *cough* "private negotiations" *coughcough*
For combat, there's an old system from an RP I was in a while ago, in which combat scenes were handled by presenting the enemy NPC's actions to the character they're facing, allowing that person to react accordingly, then the GM would act as the NPC in their post, seperate from their own character. The person will choose how to react to being shot at, though some hits will. Combat will favor our characters for the most part (nobody wants to die in their first post, after all)
The Highlander's feet slammed into the ground as the machine was pushed forward, hurling itself at the oncoming Atlas as it just began to turn to face its opponent. Raising the 'mech's left arm, Jack let loose with the twin tubed Streak SRM launcher there, holding the crosshairs of his targeting display over the massive battlemech's broad chest, even as the enemy began to raise its arms in reply. With the crosshairs flashing gold, the ninety ton assault 'mech buried its foot into the ground as it cut to the left, smoke and flames flashing from its left arm as the two rockets lanced forward, corkscrewing in toward the Free Worlder.
Smoke rose into the air as the short range missiles slammed into the Atlas just as its own missile launcher coughed flame and smoke, sending six SRMs back at its opponent even as chips of armor were flying off of its center and left torso. The two small missiles had done little to harm the one hundred ton death machine, though the more accurate Streak model SRMs seemed to give the Striker's Colonel an edge in the exchange. As the six missiles rocketed toward the target, it was clear that the quick change in direction had thrown off the targeting computer, leaving the group of missiles to lag behind their intended target by a half second.
Jack flinched as he felt two of the missiles slam into his right side, gouts of dirt and flame rising into the air behind his 'mech as the other four cleanly missed. Keeping his torso lined up on the enemy, he brought up the 'mech's right arm, barely allowing the computer to flash gold on the targeting crosshairs before pulling on the trigger he held in his right hand, sending a lance of azure lighting back at his enemy, followed by the ruby spear of his large laser a half second later. Heat spiked in his cockpit as both of the energy weapons were fired off, though even as sweat broke out across the man's temples, the heat sinks were beginning their work of cooling the 'mech, dropping the cockpit temperature quickly.
Where the Atlas had simply shrugged off the smaller missile impacts, it staggered as it took a step forward, taking the brunt of the charged and accelerated particles to its right shoulder, tearing a deep gash in the armor there, but the weapon seemed to refuse cutting through every layer of the armor protection there, leaving a carbon scored scar across the 'mech's almost hockey-like shoulder pauldron. The red beam of the extended range large laser pumped megajoules of energy into the 'mech's right arm, slashing a deep cut across the Atlas's bicep, lasting long enough to leave a carbon black slash across the right side of its body before the beam dissipated. Recovering from the hits as only an Atlas could, it would raise its arms toward its enemy, lashing out with all four of its medium lasers.
and so on and so forth. post order will only affect those in combat, to keep them from posting an action, then suddenly going off and doing something else before I have enough time to respond to it. Just remember that if your character does something reckless, it will reflect on what will be dealt to it. If I feel there are too many misses, an autohit will even things out, though I don't expect to have to do that at all. Otherwise, if just talking, the posting order will simply be to wait for whoever you're interacting with to reply. It would be rude to skip the other person if another person starts talking to your character.
