If you've been waiting for Fatshark and Paradox Interactive to release Lead and Gold: Gangs of the Wild West for XBLA, wait no more - in an interview with Joystiq, Paradox CEO Fredrik Wester has said that the project has been put "on the backburner". He noted that it's unfortunate; "but you know, things happen. We love XBLA and would love to be on it, but with Lead and Gold, we just have to move on."
Which means that if you want to play the game, you'll either have to pick it up on Steam for PC or on PSN for Playstation 3. Sorry, Xbox-owners.
