I confess: I've been doing some tweaking to the games I've been running and I'd be proud to share them here. In exchange, I'd be interested in seeing what cool modifications others have come up with. Is it appropriate to start a community-wiki thread with a title like "What are your GAME X house rules and modifications?" and let people go to town, or is something with such little guiding focus better for another site?
I really don't think that such a question, even on a per system basis would be very useful to anyone.
Such a question might be ok if
- It was community wiki.
- It was system specific
- It was asked with regards to a specific mechanic.
What are your house rules for differentiating firearms damage in d20 modern?
Basically, keep the questions specific.
Your question is why the community wiki feature exists. The only suggestions I have is limit each post to one system as it will help fans of that system find the posts easier.
Personally, I would rather have system+topic specific questions, but that may just be personal preference. I think that as long as it doesn't duplicate an existing question (there are a few houserule CWs out there) that it wouldn't need to be closed. People can vote on it to express preference for such a general question.
Hosue rules is a problematic tag only because it requires another tag to exist. Theres a good policy on stackexchange to avoid tags that can't surive on their own and are subjective (http://blog.stackoverflow.com/2010/08/the-death-of-meta-tags/). Hosuerules probably qualifies and we should remove it as a result.
I'd much rather see a question like, "Where can I go on the net to find lists of house rules?"
