Solid plat-former that's good but won't blow you away like that time your mom found your weed stash
Jump over the gaps, unlock some characters you don't care about, collect some floaty orb plant-life things, don't get eaten by other lifeforms and don't get smashed by shifting landscapes. The gameplay is smooth and has the core-elements that makes a plat-former good. However there's just not really any innovation anywhere to make me call this game anything but a time killer and once you've realized you've been killing too much time playing video games and not doing something else more productive, you'll quickly forget Rayman Origins.
This isn't a bad thing. My life centers around time killing games. And for a game to have somehow been thrust onto this sort of high-standard bar of which I call, "time-killing games," then there must be some interesting or eye-catching qualities about it. What Rayman does the best is keep it simple and keep it fun. Completing levels don't give you that "Holy McGoverns I'm a God" sensation like completing a level of Ninja Gaiden for the NES does. But they keep the time moving from one position in your life to another. And I guess you can look back on those moments and feel you didn't completely toss those life chunks down the toilet.
Time to Kill? Play Rayman Origins.
