I developed a board game nearly 20 years ago that is still going strong within my familly and friends.
I attempted to get it marketed back then, but the legal guy I saw seemed to be rather a plonker. Now we find ourselves in the e-gaming time, I wondered how I would go about getting my board made up into a pc game.
All I can think to do is write to a computer/console games company and ask them if they'd be able to help you. You really should either patent or copyright it first though, there are some very unscrupulous people out there. Sorry I can't help more, but that's what I'd do.
