I just wanna say that many of us are not 'stupid or blind' as you so bluntly put it. Many of us buy 3rd party games. we just don't buy poor quality ones.
I'll back this with several examples: look at the recent nintendo 'players choice games' 007 Nightfire, Rogue Leader, Resident Evil Rebirth, spider man and sonic battle 2, thats 5 out of 8 current PC games that are 3rd party.
Second, many of us support other 3rd party games as well or else there would be no monkey ball 3, burnout 2 or LotR-Return of the King comming soon.
Here is a list of 3rd party games I have (out of 18 games since i got cube in dec '01): Rogue Leader, Dark Summit, Monkey Ball 1 & 2, Blitz 2002, Timesplitters 2, star wars bounty hunter, lord of the rings 2 towers, resident evil 0 and I plan to buythese 3rd party games over the summer: burnout, splinter cell, soul calibur 2, sonic mega collection and skies of arcadia. Half of my current collection and over half of my planned summer purchases are from 3rd parties. don't even get me started about next fall/winter and 2k4...
I'm sure many others here have supported QUALITY 3rd party games as well (not saying all of the ones I got were quality...dark summit was my only impulse buy ever and bounty hunter was a X-mas gift...both were worth renting, but could've been much better).
3rd party games sell if they are good, thats the lesson of the day. outside because its funner IMO. So don't bring down the finger of blame on us when it isn't necessary or justified.
