“AVOID THE SHINY
This isn’t original with me or unique to online gaming. But it is still good advice. For the most part, you should avoid too many campaign reboots, rules changes, or genre switches in your regular game. It’s much better to work around any quirks in your particular rules system (or post some house rules) than to ask folks to change editions or systems frequently.
Now, some groups may be fine with an occasional one-off in another system or genre. In general though, if your dying to run something different, you may want to just run it at a different time and send out a general invite to your social group. While your regular players may want to play, they won’t feel obligated to play something they are not interested in.”
