Depends one what you call a"Good Game", I really hate most of Xbox's games just because there are completely uninteresting and just "copy of's" of every other game. The PS3 is yet to shine, it may not be the best thing right now but the technology will out last the Xbox 360, which should I remind every one is owned by MICROSOFT.
The PS3 may have a more advanced processor than the 360 and yes it can fold proteins like a demon, but relative to gaming it's "extreme" power is rather useless, if not a negative.
Because it uses such a unique architecture for it's processor(s), it is difficult to develop games for it, especially when you consider that the 360 uses XNA architecture which basically means that it is very easy to port a game from the PC to the 360, or vice versa.
Other limitations include the fact that many people lack a TV that supports 1080p resolution and even then that pales in comparison to what some PC's can achieve. Most games seem to support 720p rather than 1080p on either console anyway.
Considering the recent price drops of both consoles and the release of some really cool games, I'd say both consoles have decent values right now. The 360 has almost completely recovered from the RROD-pandemic and the PS3 finally has a few decent exclusive titles to stand on. Blue Ray may be the victor in the HD format wars, but so far consumers have been hesitant to choose the pricier Blue ray movies over their cheaper DVD counterparts. Also, there are now many Blue Ray disk players available for less than the price of the PS3.
Even though I can heartily praise both the PS3 and the 360, I can't offer the same praise to the Wii. It's technology was far from innovative (motion control tech has been around for many, many years in arcades) and it's severe reliance on first party games has placed it in an awkward position. Every title seems to collapse in on itself and numb itself down into a very plain series of minigames fraught with a collection of wildly pointless gestures needed for basic gameplay. I feel it's success can largely be attributed to it's lower price point and it's collection of games appealing to a younger audience. Successful? yes. Innovative? no.
