Okay, I read through some of the original comments in this thread and I think we got a bit off topic, arguing some moot points.
The original complaint was that PC games are getting harder to find, and comments were made that they're dropping off the map. Now, I don't think this is necessarily true. I do think PC games are not being marketed very heavily at all, and PC-exclusive games are barely being marketed at all. But they are out there, and I think the PC is becoming a haven for good budget titles. The PC is also the only place you can really get true simulation games; you can't get things like Flight Simulator on consoles, there's no market, and even things like NASCAR racing sims aren't as deep on consoles as they are on PC. Grand Prix Legends is still considered the bets racing sim -- as in pure sim, not Gran Turismo sim -- ever made, and it's over half a decade old.
Yes, the PC is a platform for specific types of gamers. There's also an interesting polarization, with numerous budget titles next to extremely demanding and beautiful games like Doom 3 and Half-life 2. A lot of thegames that work on consoles don't work on PC's and vice-versa, just because of the way they're designed. They're two different markets for the most part, and that's okay. When titles do crossover, you can bet they'll potentially look better on the PC -- if you have decent hardware. Vice City looks exponentially better on my computer than on the PS2, and I don't have a $2000 machine.
Hardware seems to be what it comes down to. And when it comes down to it, many people make comments like those that were made in this thread, about having to buy $600 video cards every month. I think we all know that isn't true. The difference in price between a PC that can display console-level graphics and a console isn't much, if there is a difference at all. I already explained that to be fair we have to consider only the cost of makinga computer sufficient for gaming, not the entire computer itself -- so while it may cost $800-$900 for a gaming computer, only $300-$400 of that at most is dedicated to gaming performance. The life cycle of such a system is also comparable to the current 3-4 year cycle of consoles, so comparing the cost of a new console, which is usually $300 (and in the case of the PS2 is rumored to be significantly higher), with the true cost of a gaming PC shows that if it is more expensive, it's not much more so. In addition, PC's have a vastly larger library than any current console, even considering the PS2's backward compatibility, so it may be more true to compare a gaming PC to two or more consoles!
I don't really understand why the price factor is so important in the first place. As I said before, nobody claims that the Gamecube is so much better than other consoles because the other consoles are so much more expensive. Comparing the Gamecube's price to the XBox or PS2 is making the same argument as comparing the price of a gaming PC to a console, but for some reason, the people who making the cost argument against PC's don't make that same argument for the GC. That's because when you really getto the bottom of the issue it's about what games individual people want to play. If it costs $400 to play PC games, people will still buy the hardware because they want to play the games that are only released on the PC. If it costs $400 for a PS2, people will still buy the hardware because they want to play thegames that are on the PS2. For PC gaming to die, the market must die, and that won't happen any time soon.
The PC does have certain advanatges. There's no comparison to keyboard and mouse for pinpoint accuracy in FPS's, as anyone who has spent some time with both that setup and controllers will tell you. The PC's massive amounts of storage, while arguably only a current advantage that may not last too much longer, allow different types of games to be designed, and the natura of a PC (as a multi-use peice of equipment) means that certain functions, like Internet connectivity, are assumed. This allows for things like patch and map downloads, things that are just becoming available on consoles, where they aren't anywhere near as widespread as on the PC. PC's are also fairly easy to develop for (no complicated licensing), so there are a ot of offbeat, inventive games out there that would never hit consoles due to budgetary concerns. Consoles have advantages, too, mainly ease of use, but many many others, like household reach. In the end, PC gaming is just a subculture of gaming culture, just like any hardcore group of gamers.
