Most everyone has been following the rules set in the topics. The games forum has been going quite well

The only topics currently locked in the forum are duplicates of other topics. Topics don't get locked in this forum unless they are a duplicate or are breaking other rules, people can always post on them as long as they follow the rules of the topic.
We don't do this for every forum because commonly (before we had auto-locking of topics) the only people who would post on topics with no posts for 2 weeks on them, were new members to the community with a pointless post adding nothing to discussion. The same thing can't really happen with forum games as there is no real discussion.
With the current rules, you shouldn't have to make a new thread for the same forum game again.
I can see why for some types of games that people would like to start over. For example with the RSBANDB Novel, people might want to start over with a new story, but that is currently disallowed.
Reasons for allowing duplicates or how a topic is determined as finished may be discussed in this topic.
