I would play any game as long as the game is simple and everyone knows the rules and they were posted at the beginning of the thread. It would serve as a reference and a way for everyone to know what happened when they roll the dice. I do 2d6 with evens as success and odds as failures. I make each I individual number a degree of success or failure. Each holds a percentage marker of significance of time, damage, and percentile for damage ticks are rolled each turn when each player or NPC turn is taken or by the spell description of tick frequency. I use Rory dice to help make a storyline and scene. I also like to keep actions liberal as long they can do so by indicator markers as decided by the rolling off the dice.
