erm...guys...your forgetting a few factors.
while true a pc generally IS more expensive, that is due to the fact that a pc can do much more then a counsle.
a counsle can play games great despite having hardware that is easily ancient or old by PC standards simply because it is programmed to do that and only that. whereas on the pc the hardware does much more stuff then just boot up from a game disc and run the game.
as for me, i'd take a pc over a counsle. on a pc you can MOD the games, which in my opinion is a vast benefit to pc gaming since if you get bored of the game or have done everyhting in it, you can download a mod that can completly change it or add new things. many games have mods released, oblivion, gta 3/vice city/san andreas, the whole sims and sim city series, half life, and lots of other games. these aren't official mods either, these are mods made by players.
theres also the fact that you can do so much more on a pc then on a counsle. sure, a counsle can do media playing, internet access, and gaming. but can you do your taxes on a counsle? what about 3d modelling or video editing? how about fixing something when it breaks or upgrading? its easy to upgrade a pc or replace a busted stick of ram in a pc. the only way to upgrade a counsle is to buy a new one.
how about different formats?
when it comes to gaming on pc, the main format that a vast majority of pc users have is windows, and knowing this, developers release games lots of games for it. no matter what brand of pc you have, you can play the game if you have the right hardware.
for counsles you have...well, every counsle on the market. not all games are available for all counsles. kinda limits your gaming unless you buy each counsle, but then the cost would be well over that of a pc.
how about backwards compatibility?
pretty much any pc can play any older game as long as it meets or exceeds the requirements of that game. thats ANY game, even games from back in the early 1990s. find me a counsle with that kind of backwards compatibility.
so...when it comes down to it...
a pc is backwards compatible with the earliest games made for pc, and it has only one main format that games are released for. thus you have a selection of thousands, if not millions of games to play on a computer. then if you mod them, that number grows even more.
having a single counsle will cause you to have a much smaller selection of possibly less then a hundred games to play due to the fact that different counsles use different formats and have even used different media types threw the years which drasticly limits backwards compatibility.
(p.s. yes, i know i didn't bring up linux or macos. but then, i know little about them so it wouldn't be right for me to talk about them)
