Fortunately,
R2R is anything but annoying. Fun? Yes. Entertaining? Yes. Frustratingly challenging? At times, absolutely. But it's got the proper mix of 'just one more' playability and a silly plot that nonetheless will have you keep playing. Despite some issues with the overworld map, at its heart
Rayman 2: Revolution is the same game we all loved when it originally came out.
Therein, of course, is the game's main fault -- despite the additions to this PS2 version, R2R is really still just Rayman 2. That's not necessarily a bad thing, but it's hard to justify picking up a new version of a game you've already beaten on another console.
For those of you who have never played Rayman 2, a simple description is in order. Pirates are taking over Rayman's world, and it's up to you to help him save it. Of course, all of his friends have been kidnapped, and you've got to save them. The game itself lies somewhere between Super Mario 64 and Crash Bandicoot in its linearity -- the maps themselves are relatively free-roaming, but there's a definite order as to how you complete them.
Rayman starts out with few of his normal powers -- he cannot grab rings, his fists are weak, and so on. As you progress in the plot, you pick up all of these and more. Oftentimes the skills that you gain are necessary to fully complete a level that you've already gone through, which means that backtracking is rarely necessary but highly encouraged nonetheless.
There are some enhancements to the formula from the original computer version to this PS2 version. There are some added challenges and levels -- for example, after saving three guys in cages, you can go to a rollercoaster level. The overworld map has been replaced by an actual exploratory world, a la Spyro. This is both a blessing and a curse, unfortunately -- some of the largest amounts of slowdown in the game appear in these overworld maps. And instead of having some handy-but-unnecessary skills for Rayman from the start, you buy them with Lums that you collect throughout the game. This sort of upgrade method is a Good Thing, but it still feels a little tacked-on. It's still quite a bit of fun, though, especially once you finally get Reflect.
