Cost is not a drawback, because you don't have to go overboards just to play a game. It annoys me to no end when some people insist on buying components for over 1500 dollars to play games and then complain about the price, when the games they play would have run at a computer that cost half of that, and still perform and look better than they do on consoles.

If you don't complain about the graphics on your console games, why do you need a computer that plays them in twice the resolution, twice the framerate and a ton of extra graphical detail?

In either case, the drawbacks of PC gaming, for me, is that some genres aren't well represented, and that compatibility isn't always 100% perfect. A console game is almost guaranteed to work the same on all (non-defective) consoles, PC games are still quite a bit away from this level of compatibility.

Also, like Pike already said, I already have a desktop PC (because laptops just don't have enough space and power!) to use for non-gaming purposes. The parts in my computer that make it able to play all the newest games costs less than a PS3 does. Even upgrading my PC to play the newest games in even better graphics won't cost me more than a PS3, and it is about two years since i bought my current graphics card. Of course, I don't actually *need* to get a new graphics card, because I play all the new games in a lot better quality than on consoles already. I just want to play them even better cause I am a graphics whore and the PC gives me the flexibility to feed that addiction.
