20: Tom Clancy's Rainbow Six Vegas 2

What happens in Vegas usually doesn't consist of men with guns rappelling down the side of the MGM Grand, tossing smoke grenades as they blindfire terrorists, but thankfully we can live out that fantasy again and again with Tom Clancy's Rainbow Six Vegas 2.

With unprecedented squad-based tactics and adrenaline fueled action from the moment you pick up the controller, you'll never quite look at Sin City in the same light.

19: Rock Band

Picking between the PS3 and Xbox 360 versions of Rock Band is pretty much a toss-up. The 360 has a better online structure, with downloadable content available days (and sometimes weeks) earlier, as well as a larger pool of opponents to battle against, but those benefits are dwarfed by the PS3's packed-in wireless guitar.

You may be able to buy wireless guitars for the 360, but the wired one that came with the game will always haunt you. So do yourself a favour and pick up the PS3 version to avoid all that.

18: Burnout Paradise

Criterion Games continually churns out excellent PlayStation products, and it's the same with Burnout Paradise on the PS3.

Lighting-fast auto racing lets you speed through the twists and turns of Paradise City in a flash, and smashing up your precious ride is once again part of the fun. And this time there are no boundaries. Plus, downloadable updates have added to the destruction, dropping in motorcycles and other updates. And rumour has it planes are next!

17: Ninja Gaiden Sigma

Ninja Gaiden II was pretty stinky. Now it seems more clear that Team Ninja's finest work was the PS3's updated, upgraded, and unparalleled version of Ninja Gaiden.

You really can't go wrong with the intense action of the Xbox classic and the amazing new visuals put forth by the PS3. Normally, we're not fans of developers rehashing old titles, but when this is the end result, we're willing to let it go.

16: PixelJunk Monsters

This quirky 'tower defence' game first appeared on the PlayStation Network with a few raised eyebrows. Don't let the cartoonish art style of PixelJunk Monsters fool you, though — beneath the unique and innovative hand drawn art laid an extremely addictive real-time strategy game that to this day, still has us going back to research, build, and upgrade our bases.

15: Everyday Shooter

All three consoles' game-download services are packed to the rafters with shoot-em-ups, to the point where many great games get lost in the glut. If you've got a PS3, we implore you to not let that happen to Everyday Shooter. Part shmup, part rhythm game, part puzzle game, Everyday Shooter is an amazingly unique and distinctly stylish title that should be one of the first PlayStation Network downloads you make.
