Well, firstly, you can't compare a game like Crazy Taxi to UT--it's just not fair. My GF's brother has DC and I really enjoy Crazy taxi. There's a lot more to it than "driving badly" and dropping people off. A comment like that is on par with saying Street Fighter is just two people kicking and punching each other. You're being reductionalistic and that's not fair to it. You said you liked the different weapons and routes to take; CT has different vehicles and short cuts to take. They are differnt games, and sure CT may not be your favourite game, but your opinion is definately a minority one. This is besides the point however.
Another problem with your argument is that you say that unique games come out on the PC first. This opinion is based in ignorance I fear. For one thing, the xbox has literally hundreds of developers and many of those developers have stated that they will now develope for consoles first, PCs second. Tony Hawk (pretty innovative) first appeared on a console. What about Resident Evil? Ground breaking? Yes. On a PC first? No. Final Fantasy (a game which renewed interest in RPGs) appeared first on a console. Crazy taxi, like it or not, is pretty damn innovative. Jet Grind Radio, Seaman, Mario Bros, Sonic, Zelda, Castlevania etc. These games all started on the console and are great innovaters in their genre. PC games are unfortunately relegated to racing, FPS, and RTS games. You'll never see a decent Street Fighter game, side scrolling game, shooter, mario type etc. Capcom, Konami, Square, Sega, Nintendo, Acclaim, Rare (and countless others)--how any games from these undeniably great developers develop for PCs (Sega does, but not their recent games). Variety exists on consoles, so does innovation--just because you deny it, doesn't make it false. It seems that when people argue for something that they believe in they are often blinded by the facts. I love PC games, but I don't close my eyes to the benefits that a console can deliver. The Xbox isn't even out yet, no one in the world has seen a game let alone played one and already you guys are denouncing its viability as a game machine. I'm not going to say its going to be great, but there is a good chance it will and I would like to be open minded enough to consider the purchanse of a $200 machine that can do as good or better than your $2000 machine.
