Hi,
I know a game available for pc and iphone. It's not even a very recent game, however there isn't any online and/or facebook version of it. Imho, the concept has a huge potential for social gaming.
Question is, how legal is if I was to do clone of the game, extend to be a social game and publish it on facebook?
There is excellent advice on this subject from Tom Sloper: <a href="http://www.sloperama.com/advice/faq61.htm" rel="nofollow">http://www.sloperama.com/advice/faq61.htm</a>
