Where we're to post in existing threads about particular games and to make posts related to those games in their own thread instead of posting in more general topic threads.
A couple people had their butts jumped over it in the past for making new threads about games that already had them but refused to search them even though they knew they existed.
No there's never a problem with making new threads for new news. Threads are awesome!
However lots of times there is news that really isn't worth making an entire thread about. Case in point these new Halo pictures that were released this morning. I was going to post them in the XBOX community thread, but then decided to make a new thread instead.
