Microsoft pissed me off even before the launch of the Xbox. If you were a PC game player then maybe you remember the way they hyped Halo as a PC game in all the gaming rags for several months. Then after they had gotten all the press and gotten all the PC gamers excited they pulled the bait and switch, anouncing it would be available only on the Xbox.
Sony has thousands of titles for the PS and PS2 this is true. The big problem there is you have to sift through about 100 POS games to find one single gem.
Nintendo has been kid/family geared since the start. The number of titles is limited for sure but luckily a high percentage of them are very fun and playable games.
I will be interested to see how this generation plays out.
