It's kind of questionable whether it should be in blog or a forum. It could be in a blog, but I don't really find many general fandom threads. Failling to find one means this should be able to stay, but if there is one, a reply to that thread will be just fine. And yeah, UN2 was pretty awesome, but IMO, UN3 totally rocks even more than that.
These topics don't break any rules. *Now if someone is continually spamming the forums with topics like these that's a problem, but otherwise it's okay.
I also don't see a problem with it. Not everything has to be regulated to blogs! At least this topic is about the right game unlike about 90%+ new topics that get started in the Ulttimate Ninja 2 part of the forms
