Hi I like to say something as to the OP idea of the thread. I know we are talking about game ideas and unique mechanisms. When this forum was flooded with flash newbies we would get every week the " Lets all team up and make a clone of -X popular- game." I posted once making fun of this group with a silly idea that I will restate here but Also include a area that I think is under served in gaming.

So in vain of the Scary Movie franchise I like to suggest the comedic parody games. There is always that popular game line that "you" may just not like. At the time the newbies were posting that game for me was the GTA set. So I suggest a parody making fun of the whole idea of GTA set in medieval time, call Grand Theft Horse GTH. But I was really thinking now that a cool game would be a combo parody were it is making fun of a different popular game in each level.

Ok long post for my 2-cents.
