I've had two ideas running through my head for a while and so yeah.

Midievil zombie apocalypse would be interesting morning stars, broadswords, etc.

Then the western zombie apocalypse I've actually done with a friend on another site. A group of survivors having had taken refuge on a train known as the Bloodhorse.

Either would be great, a great spinoff of the usual zombie forums. I'd join either one..you know how I loove medieval and I have never actually done a western type thing..could be interesting.
