They may have, but there's so many rumblings about stupid things getting movies all the time, it's easy to filter out. Most of them are just troll pranks anyway (like Space Jam 2 was).
Now someone's going to rehash the tired "Hollywood is out of ideas" line again. This time I'll agree to a small extent. Hollywood is running out of things to license out as movies. And Nintendo brilliantly decided to not license characters out to anything but cameos in Wreck it Ralph and Pixles because of that one horrible movie... then again, they HATE any fiction Japan doesn't produce. Like Pokemon is high art and any Mario cartoon is an embarrassment.
There are certainly denser, bigger, plot driven video games out there to do a movie of. I mean we can forget a Halo movie, and I'm sure the Ratchet and Clank film, if it even happens, will be DTV or something. But OOOH! Big Budget Tetris film no one's going to see, not even ironically. Makes perfect sense.
