System games..... I have played a lot of board games and I've played D&D a couple of times, and I seem to recall that the most basic system for PvP combat is what I think of as "To-Hit/To-Kill".
Basically, you roll a dice against your weapon type and skill, modify it by the target's size and dexterity, modify it by your own dexterity and if the modified roll is lower than the hit number, you have hit your opponent.
Your opponent then rolls against their armour class, modifying the role by target facing, and takes damage based upon the amount by which the roll exceeds the armour class.
I'm sure people know this system. It's basic and it works in just about any situation from swords and sorcery to tank battles, to space battles.
My question is, what is the best way to implement it in group game in E?
The problem I can see is, that if you have two equally matched opponents duking it out, the combat could last for several rounds and the worst case scenario is that one of them posts once a week...
My best idea for this is to ask both players to submit (say) 5 rounds worth of dice rolls at the start of the fight. They both put in a hit and damage roll for each round, regardless of the result of the hit rolls. These are then matched up and the result of each round worked out.
The disadvantage to the above is that if it becomes clear that you are going to die, you can back out. The only way of preventing that is to maybe specify that players must fight for a minimum number of rounds before they can attempt to withdraw, and attempting to withdraw requires a dice roll, and gives the other guy a free hit, meaning you might just die anyway...
So, is this workable?
The follow-up question is, how do GMs like their players to post this sort of fight?
My ideal solution would be to have both players PM their posts to each other, work out the outcome of the fight and then both post opposite sides of the same fight, covering it all in a single post, rather than have them post a string of "blow-by-blow" one-liners. Again, does this work?
