It is common knowledge that many games are dumbed down for consoles.
Really? Which ones? I guess RTSs get simplified control schemes, what else? I'd love to see PC gamers tackle something like Ninja Gaiden though, given how retardedly easy PC games are, they probably couldn't take it. Of course, that has nothing to do with control schemes, just lousy skills.
Look how many PC sequels are ruined when they are simplified so console users can play them.
Like what? Let's get some examples going here. I have hundreds of PC titles and console titles, owned almost every gaming platform ever, please point out these games. Feel free to list exacting examples too. Elder Scrolls saw a fairly huge improvement in quality although the games became far more difficult to actually play through when consoles became a priority(ES:3 took all of what, an hour to make yourself a god?).
I guess if you are into the aim assisted style shooting for FPSs, PCs work nice, mouse/kb isn't quite as nub as a controller, but nothing like actually having to aim. I was a big fan of kb/m for shooters until I tried the Wii- actually have to aim>>>>>>>>>>>>mouse.
Racing games on the PC overall are a tragedy, they can't come close to the consoles offerings on... well..... anything. Even the 'strong' PC category, sims, aren't remotely close to an actual simulator(I own a few of the cars that some of the 'best' PC sims have used, and they aren't remotely close to right on handling dynamics, looks like they read a magazine article and guessed).
Sports games, hehe, yeah right.
Face to face social games- errr, I guess the die hard PC crowd wouldn't really have any need for that whatsoever- they don't do that human interaction thing.
Adventure titles- yeah, 20 years ago the PC did OK here. Lately? Sorry, consoles utterly obliterate PCs.
Fighting games- uhm, did the PC ever really have any? I know, requires reflexes way too fast for the typical PC gamer, 1/100th of a second reflexes may get you into a pre school tourney, if you are lucky. PC gamers have trouble realizing how 10ms ping would completely ruin a good fighting game, they just don't understand that that is a lifetime to a skilled gamer.
RPGs- Yeah, PCs have the 2 big MMOs worth playing- everything else is either on both or only on the consoles. Overall, consoles are the better platform for the genre(I am more then happy to hear of exceptions to this- even Fallout has crossed over).
Action games- the PC tries hard, almost good enough for a medal..... if this were the special olympics.
RTSs is the one place where I would say that PCs have a very clearly defined edge. Every other genre the consoles are comparable if not obscenely better then the PC. Like I said though, I have multiple games libraries, feel free to cite specific examples as to why what you say is true about PC gaming.
