Hopefully some of you will remember this game from the old forum, so that I'll have to explain it less. Basically, I start off by posting a picture, and the person after me posts a picture of something which could conquer, destroy, kill or otherwise defeat the thing in that picture. The person after them finds a picture of something that could defeat the thing in that picture, and so on and so on.
You shouldn't have to explain why the thing in your picture could destroy the thing in the previous poster's picture in more than one or two sentences. In fact, it's best if you don't need to explain it at all. The thing in your picture should have some advantage or niche over thing in the last picture, so say for example, if someone posts a picture of a dinosour, instead of just posting a picture of a random monster and saying that it could take it out, try posting something that a dinosour might have a weakness to.
This does not nessicarly have to be a
real weakness. For example, in the 1998 Godzilla movie, godzilla (who is a dinosour like creature) was killed by being lured into a powerline, so you could post a picture of a powerline in response to a dinosour, and use "Godzilla"'s climax as the rational behind your choice. Alternatively, it could be a real* weakness of PP's picture, for example, you could also respond to a dinosour with a picture of a meterorite (one theory of the dinosours extinction was that the Earth was hit with a meterorite, causing an ice age).
If anyone needs to know how to post pictures, just ask. It's very easy; people who can't do it are usually not managing simply because they are making very small mistakes. Try to be creative, and keep the battle running long and hard!
And now, for round 1;

Stalin's on the rampage; what are YOU going to do about it?
