Turning Clue into a movie wasn't that much of a stretch. You already have a premise of a murder mystery in a big mansion full of weird murder weapons and secret passages. You even have names and pictures for six main characters, so it wouldn't take much work to fill out a personality to match. Since Clue was just a game adaptation of all the murder mysteries that came before it, turning it into a movie almost made sense.
Next you've got monopoly. Okay, I'm assuming it's about a bunch of guys trying to buy up property and bankrupt each other. Maybe one of them even goes to jail. I'm sure you can put a bunch of locations in the movie like Marvin Gardens or whatnot to give it that monopoly feel. It's a bit of a stretch but I guess you could make a movie that relates to the board game, though I can't imagine it'll be much good.
Then there's risk. Though I pray it's a joke and not something they're seriously considering. Now it's been a while since I've played but as far as I can recall it's six colored armies (not countries, or political factions, just colors) and you roll the die to see how well your colored tank attacked the opposing colored tank. I really don't see much of a premise here. There's nothing to base the movie off of; nothing to draw from. Anything that you would need to have an actual plot for a movie (characters, political organizations, motivations for world conquest, etc.) you'd have to make up, so what would it have to do with the original board game other than sharing the name?
This sounds like "We have a really awful script for a war movie that we're never going to sell. Let's see what kind of Trademark we can buy up and slap on this piece of crap to make it half-way sell-able."
No, this is the death of Hollywood. For the last decade it was comic books, now it's board games. Crap board games at that. They've really got nothing left.
