After both a rough launch and a drought of games, the PlayStation 3 is finally emerging from the desert with some incredibly strong exclusive titles and, after the recent death of HD-DVD, domination of the home-theatre market.
Little Big Planet and Metal Gear Solid 4 are the PS3's flagship titles, and given their outstanding quality, are the most compelling reasons to pick up a PS3. The other, and probably main reason for a lot of buyers, is that the PS3's also a Blu-ray player. For many PS3 owners, the fact that the PS3 is a gaming system is secondary to its Blu-ray capabilities.
The PS3 still has a long way to go before it can dethrone the Wii and Xbox 360, but for those interested in making a major addition to their home theatre, it's the obvious choice.
