If you are serious...you don't know much about PC gaming. Map building and mods are plentiful for many games and I've never touched an RTS game or a MMO.
map building and mods for what? FPS? they have map builders on the console as well.
There isn't much a PC can do that a console can't do, as I said aside from RTS/MMo's you can play everything on console with nary a difference. Sure a pc port will have better graphics, and controls that you can customized, that's obvious when you're comparing a computer built for gaming starting with at least $600 vs. $200/$300 console. What's the argument? FPS is better on the PC? well of course but the same game on a console sells better than a PC counterpart, pretty much a multiplatform FPS will be
xbox360
ps3
PC
in terms of sales, why? the experience is better on a PC, that weeny ass thumbstick is so imprecise it feels like that is how the game cheats to kill you, with an inferior pointing solution. It's cuz for the price of a PC that will run at the same graphics as a console just doesn't seem like such a great deal.
Kids don't want to troubleshoot problems no more, they just want to play, why do most of us know command lines? cuz we had to get that damn EMS 386 upper memory so we could play those DOS games, kids now a days have a mac laptop and an xbox why bother with a PC.
