Mashable is looking at certain patents that Google has recently filed and wondering: Is YouTube about to jump into online gaming?

...the Google patent seems to detail a system where the creation of video annotations can be used for gaming-like mechanics and video behavior change.

On first blush, it sounds like Dragon's Lair to me. But if YouTube does become a platform for casual games, Google could change/elevate/destroy yet another industry in 2010. Something to look forward to!

And if speculation isn't your thing, you should try playing this incredibly difficult Super Mario Bros./Tetris mashup instead.
