The GBA game's multiplayer features are fairly limited and poorly organized. Its single-player component, on the other hand, is very nicely organized and offers a great deal of variety.

Chaos Theory sometimes has a designed-by-committee feel due to its many disparate parts, and despite the game's grittier new theme and its new "Mature" rating, it's going to offer a familiar experience to Splinter Cell veterans. But even if some of the changes are marginal, this is still the most entertaining, most well-rounded game in the series yet.

While the online play is merely average at best, its single-player play, as well as its overall production values, present themselves as seriously subpar.

Provides a very rewarding way to relive WWII from the perspective of its top leaders.

Neither especially tactical nor satisfyingly action-packed.

With its surprisingly awful fighting mechanics, busted-up frame rate, and bare-bones gameplay, Iron Phoenix is just a colossal waste of time.

Dogged by a number of graphical issues that often interfere with gameplay.

Probably the best portable fighting game ever made.

A colorful cast of characters, a great presentation, exciting shooting action, and support for wireless multiplayer competition over the Internet combine to make this game one of the safest bets you can place when choosing your first PSP games.

It's a trite and aggressively boring version of what a million other third-person action games have done. And even for its budget price, it's a pretty lousy value.

Up to 16 people can play online, and there are several different modes of play. While this might sound like a pretty good deal, the unbalanced shooting mechanics and mostly lousy maps pretty much do away with that notion right away.

Because the air races found in MX vs. ATV Unleashed are so frustrating, one wonders why they even made it into the game in the first place, especially when you consider how fun the game is with two (or more) wheels on the ground.

The best handheld golf game to date. Though it lacks the online play and a few other details found in "Tiger Woods PGA Tour 2005," it's actually a better game in some ways, as it takes the sport a little more seriously.

This "remixed" version of the original delivers almost everything that was great about the console versions, and with the inclusion of four new levels, the single-player experience has gotten even better.

This isn't exactly the most overachieving action game around, but it's not a bad showcase of what the PSP can do, and it's generally entertaining for as long as it lasts.

It's simply a marvelously executed experience that's fun from beginning to end, and anyone with a taste for mature content and the action adventure genre would be foolish to pass it up.

If you strip away the patently silly drug effects and the forced attitude, NARC is an unimpressive mission-based third-person action game. It's also short, rife with bugs, and basically not a lot of fun to play.

It's got some very good qualities, but you'll need to wade through a lot of potential frustrations to enjoy them.

Considering how rich your upgrade options actually are, it's disappointing that the combat itself falls a bit flat. This is a straightforward hack-and-slash that is saddled with an unnecessary partner system and masses of foes that can be easily killed.

A short, ugly, slightly buggy, and brain-dead beat-'em-up that all but nullifies the good work of the Budokai games.

Perhaps the most disappointing (and surprising) thing about World Tour Soccer 2006 is that it's vastly inferior to the recently released PSP World Tour Soccer game, which not only plays a better game of soccer but also features a style-based challenge mode that's infinitely more enjoyable than that on the PS2.

Does a fine job of showing off the system's technical prowess while simultaneously providing more of the same smooth Ridge Racer gameplay that still holds up after all these years.

These are 10 awful remakes of old Sega games that will only serve to infuriate their intended audience.

Once you get a handle on the core mechanics, you'll find in Acid a rewarding game of strategic stealth combat coupled with a quirky, intriguing storyline and some neat points of nostalgia for the longtime Metal Gear fan.

Between the beautiful presentation, the innovative gameplay, and the excellent single-player and multiplayer modes, Lumines may very well be the greatest Tetris-style puzzle game since Tetris itself.

There's not much enthusiasm in Untold Legends. This leaves a game that, while hitting most of the necessary bullet points, is just going through the motions.

The finely tuned control that made the first game such a hit seems to have been lost in translation, but the game still has considerable charm.

If you strip away the patently silly drug effects and the forced attitude, NARC is an unimpressive mission-based third-person action game. It's also short, rife with bugs, and basically not a lot of fun to play.
