This is old news, but I haven't updated the feed in a while and it's not clear where one can go play Paper Cowboys. Though I still have it hosted on my Gamieon site, you can play it at
One other point of interest: The network engine that powers Paper Cowboys requires a paid subscription to have more than a few players. I ended the subscription and moved on to other projects. If this game somehow becomes popular, chances are you may have to wait to get in. Let me know if you do, and I may reinstate the subscription!
