@Miss-Demeanor That is a problem on games where +votes are limitless, and you have things like +room/vote. I rememer how silly it was on Metro. More restricted votes, contrary to popular expectations, do encourage the majority of players to reward the best RPers.
There will always be cliquish/circle jerk behavior, but most people on mushes don't even have 5 real friends in their inner circle, and they really do try to give their votes to the most deserving, while presenting themselves as the most deserving.
Nothing on a mush is true or false with anything more than scattershot precision. But some policies do hit more of the intended target than others.
@Arkandel Of course there is a best solution. There's always a best solution. It simply depends on your priorities. If you have one set of priorities, then the XP solution which is 'best for you', is the one that hits the most high notes and the fewest low notes that you're trying to prioritize or de-prioritize.
To my own priorities, which is maximizing activity on the grid, I find a limited vote system to have worked best. I've drawn this conclusion from nearly twenty years of observing various systems in action, and what they encouraged or discouraged. Someone that has different priorities is free to disagree with me.
But I would have reservations about anyone who approached the XP system as anything other than an incentive to encourage activity on the grid.
