We've only just begun playing. Fortunately, one of the players has much more experience with play-by-post games, so I'm leaning a bit on him. Here's what I've found so far:
- Point buy or random; not both. I'm pretty easy about character creation, and the game system really does even out power levels with the Determination point mechanism. I figured I'd let them either create the character they wanted (point buy) or roll up a character. It doesn't matter if the system evens things out: there are hurt feelings when Jack Point-buy is stuck with a 45-point character and Jill Random rolls up a 63-point character. It makes for better vibes among people if you pick one or the other. There are a couple of alternatives: Jill Random looks at her character and if the character is over 50 points, picks a limit for the highest power; if the character is under 40 points, puts an extra on the highest power; assign a higher point value than 45. But it's easier to avoid the issue.
- Pre-gens are tough to do right. Pre-gens were an afterthought with me. The players asked if I had any, and I found some I had done for a previous trial with in-person players. I did the pre-gens as random roll, and then picked some. I think I tended to pick the higher point ones. Provide pre-gens and the higher point ones get picked. I can't prove that--I've only had one pre-gen picked, but if you want to play a character, why not pick the one with more or better powers? So if you're going to offer pre-gens, use the point value as a way to make the pre-gens at roughly the same power level.
- Acting player/GM rolls 2d6-7. Yes, according to the rules, each side rolls 1d6. But what I realized is that if you post the villains or some fraction of their writeups, then each person can resolve a task in one roll.
- Don't do initiative. We're trying this. People just post when they can, and I summarize at the end of the page. I might (haven't decided yet) go for straight coordination as initiative. That would be a house rule.
- Start in media res. This whole thing is slow, so you probably don't want to have a week of "and what are you doing?" Maybe the players mention what they're interrupting to be here.
- Regular posts and a default action. Post frequently, and every character has a default thing that they do if the player can't post. Blast, recover, hide, whatever...that's what the character does if the player can't make it by the deadline.
